Why Did My Internet Bill Go Up: The Promo Ended

The increase was scheduled before you signed anything. That single fact explains most of what feels wrong about it: no letter arrived, no representative called, nothing on the account changed on the day the price did, and the search that brought you here is full of people telling you to be polite on the phone.

A promotion ending is not a price change. Your provider's standard rate did not move. What moved is which of its two rates applies to you, and the sentence that arranged that has been sitting in your service agreement since the technician packed up. Finding it takes about four minutes, and it decides what you can usefully ask for.

What follows is not a list of current prices. Those are wrong within a season and vary by address anyway. It is the document trail, the arithmetic, and the timing.

The clause is one sentence, and it is not under a heading about promotions

Comcast's Residential Services Agreement puts it in the charges and billing section, under a subheading about paying charges, fees and taxes: "If you receive the Services at a promotional rate, our then-current standard pricing will apply to you at the end of the promotional period. You should consult our rate card for then-current standard charges." Two sentences later comes the catch-all: "All other pricing is subject to change at any time and from time to time." Read 10 September 2026, on a page whose only version marker is the string Stnd0726 sitting after the survival clause. Save it as a dated PDF; that marker is the closest thing to an edition number you will get.

The same agreement does promise notice, and the wording repays attention. "Certain pricing, charges, and fees may change at any time and from time to time. In general, we will provide you with notice of any change in our standard prices or fees or new prices or fees." That covers the standard rate moving. It does not cover you arriving at it.

AT&T's Consumer Service Agreement builds the same result out of a list instead of a sentence. Section 6.4.1 says that if you signed up for a Term Plan or a Bundle Discount, that price "is valid until one of the following events occurs, at which time the price of your Service may revert to the then-current price for such Service: (1) the term of your plan expires; (2) you change your current Service address to another Service address; (3) you drop one of the AT&T services that you were required to purchase to receive the special rate; or (4) AT&T exercises a right under this Agreement to terminate your Account's ... use of the Service" (read 10 September 2026).

Two of those four are things you did. Before building a case around the calendar, check whether you moved, or cancelled a phone or television line that was propping up a bundle discount. A bill that jumps in the same month you dropped something is answering a different question, and the answer to that one is sometimes reversible on the spot.

Not every provider writes the rule down at all. Charter's Spectrum Residential General Terms and Conditions (read 10 September 2026) cover charges, billing, and a 15-day notice period for changes to the terms themselves, and say nothing about a promotional price running out. If your agreement is silent too, the order confirmation and the label file are the only documents that ever named the number.

The first higher bill is the wrong number to argue with

Comcast's agreement also states plainly: "We generally bill you monthly, in advance, for recurring monthly Service charges, equipment charges, and fees." AT&T's section 6.4.1 says the same in its own words: "During each monthly billing cycle, you will be billed in advance, at our rates in effect at the time." Your statement is cut before the month it covers.

That matters because promotions rarely expire neatly on a bill date. When one lapses partway through a cycle, the statement that alarms you often carries a split: part of the month at the old rate, part at the new one, sometimes with a prorated adjustment for days already billed. It is higher than last month and lower than every month to come.

The expensive mistake is calling on the day that statement lands and negotiating against its number. You ask for something sized to a partial increase, and a one-time credit that matches it closes the conversation while the recurring charge stays exactly where it was. Once a credit is accepted, some agreements treat the issue as settled.

So build the real number first, on paper, before you dial. Standard monthly rate for your tier, plus every recurring monthly fee itemised separately, plus equipment rental if you lease, plus taxes as they appeared on your last statement. Then subtract autopay and paperless credits if you are enrolled. That figure, the one that will repeat every month, is what the call is about.

The document that says what the post-promotion price was supposed to be

There is a filing your provider is required to keep, and almost nobody asks for it.

The FCC's December 2022 order establishing the broadband consumer label (87 FR 76959, read 10 September 2026) settled promotional pricing at paragraph 15. If a provider displays an introductory rate on the label, "it must also display the rate that applies following the introductory period," and the label "should also clearly disclose either the length of the introductory period or the date on which the introductory period will end." At paragraph 16 the Commission expressly refused to let providers park that behind a link. If you want the field-by-field walkthrough, reading the label is its own exercise.

As 47 CFR 8.1 stands on 10 September 2026 (current text at eCFR), three paragraphs give you access to it:

• 8.1(a)(2) — providers offering online account portals "shall also make each customer's label easily accessible to the customer in such portals."
• 8.1(a)(3) — every label must also be published in a spreadsheet file at one dedicated URL, publicised in the provider's transparency disclosures. Look for a footer link named Transparency, Disclosures or Broadband Labels; Charter publishes its own as a plain CSV, linked from the Spectrum policies page as Spectrum Residential Machine Readable Broadband Labels. Four of its columns answer this question outright: monthly_price, intro_rate, intro_rate_price, intro_rate_time. Read on 10 September 2026 it held 75 rows, 44 flagged as introductory, each naming the standard price its plan reverts to.
• 8.1(a)(5) — the one that matters when a promotion ends, because a provider "is not required to display a label once the associated service plan is no longer offered to new subscribers." Promotional plans are retired constantly. The same paragraph requires the provider to supply an archived label "upon request and within thirty days, to an existing customer whose service plan is associated with the particular label."

Two honest limits. Paragraph 17 of that 2022 order requires the label to show the retail monthly price before discounts such as paperless billing or autopay, so the label figure and your bill figure are built differently and a representative may seize on the gap.

The second limit is that the paragraphs above have an expiry date. On 13 August 2026 the FCC published amendments (91 FR 52251, read 10 September 2026) whose instruction 3 removes and reserves paragraphs (a)(3), (a)(5) and (a)(7). That instruction is "delayed indefinitely" in the DATES line, with the Commission promising only to "publish a document in the Federal Register announcing the effective date," so all three are law today. What takes effect on 14 September 2026 is instruction 2: a definition of "passthrough fee" at 8.1(b)(2).

The portal duty survives that rewrite as (a)(2)(ii), narrowed to your current plan. The archive duty does not survive it, and it runs out on its own in any case: (a)(5) holds the provider for two years from the date the plan stopped being sold to new subscribers. Ask while both clocks are still running.

Comcast names a second document in the clause quoted above: the rate card. Ask for it by that name, in writing, and set it beside what you are being billed.

The notice rule everybody half-remembers is about television

Someone will tell you a provider must give 30 days' notice before raising a rate. They are thinking of 47 CFR 76.1603(b) (read 10 September 2026), which does require cable operators to notify subscribers of rate changes at least 30 days in advance, and adds that the notice "shall include the precise amount of the rate change and explain the reason for the change in readily understandable terms."

Four things narrow it almost to nothing here. Part 76 governs cable service, not broadband. Paragraph (a) hands enforcement to the local franchising authority, which must give the operator 90 days' written notice before it will even enforce the standards. Paragraph (d) exempts rate changes caused by taxes, franchise fees and government assessments from prior notice altogether. And even for a cable subscriber, a promotion expiring on its stated date is not obviously a change in rates.

State law is the better place to look, and one state has written a real deadline. California's automatic renewal statute, Business and Professions Code § 17602 as amended by AB 2863 (Stats. 2024, ch. 515, effective 1 January 2025, read 10 September 2026), requires notice where a consumer accepted an offer "at a promotional or discounted price, and the applicability of that price was more than 31 days." Subdivision (b)(1)(A) sets the window: "The notice shall be provided at least 3 days before and at most 21 days before the expiration of the predetermined period of time for which the free gift or trial, or promotional or discounted price, applies." Subdivision (a)(8) lists what has to be in it, including the amount or range of costs you will be charged and at least one method of cancelling. Check your dates first, though: subdivision (j) applies the AB 2863 amendments only to a contract "entered into, amended, or extended" on or after 1 July 2025.

Then there is § 17605, which takes most of it back. Exempt from the entire article: any service from a business or affiliate "doing business pursuant to a franchise issued by a political subdivision of the state or a license, franchise, certificate, or other authorization issued by the California Public Utilities Commission," and any service from a business or affiliate "regulated by the CPUC, the Federal Communications Commission, or the Federal Energy Regulatory Commission."

Read the trigger carefully, because it is not about your plan. What has to hold the franchise or the authorisation is the business or an affiliate. A cable ISP holds municipal franchises, a telephone-company ISP holds CPUC authorisations, and both sit under parents holding FCC licences — so on the face of § 17605 the carve-out reaches every national provider. Where § 17602 still has teeth is against a smaller regional ISP whose corporate family holds none of those things. Which one yours is will be a corporate-records question, and not one a representative on a headset is going to settle.

The week to call is the one before the bill is cut

Two dates go in the calendar, and they are not the same date.

The first is the promotion's end date, taken from the label, the order confirmation, or the term stated in your agreement. The second is your bill date, the same day each month, printed on every statement, which is when next month's charges get calculated. Because you are billed in advance, a change agreed after that date usually arrives as a credit on a later statement, if it arrives at all. Agreed a week before it, the new rate is simply what gets computed.

So the working window is roughly seven to ten days ahead of the first bill date that will carry the full rate. If the promotion has already lapsed, it is seven to ten days ahead of the next one. Either way you are calling before an event rather than complaining after it, which changes what the person on the other end can do without a supervisor.

Four things to ask for, and the one that starts a new contract

Have the number you built earlier in front of you, and ask in this order.

1. The current label for whatever plan is being offered, before you accept it. Portal or spreadsheet URL. Typical download and upload, latency, monthly fees, contract term.
2. Whether the new price is a rate or a stack of monthly credits, and its exact end date. These behave differently. A rate change appears as a different line on the next statement; credits appear as credits and stop on a date nobody volunteers. Ask for that date and write it down.
3. Whether accepting the offer creates or extends a term commitment. This is where a good call turns expensive. A lower monthly price attached to a fresh 24-month term is a different product, and the clause that sets the early termination fee is worth reading before you say yes rather than after.
4. A quote for the tier below yours, with its label. Downgrading is the only lever that does not depend on anyone's goodwill. Check the lower tier's typical upload figure against what your work actually has to carry before you take it.

Ask these in chat rather than by voice wherever the option exists. The transcript is the record, and saving it as a PDF while the session is still open costs nothing.

If the answer is no, what the second bill is for

A promotion expiring on schedule is not a billing error, so the dispute deadline in your agreement is the wrong instrument for it. The exception is narrow and worth checking anyway: if the amount charged does not match the rate card, the label's post-introductory rate, or your order confirmation, that is an error, and the clock in your own agreement starts from the bill date.

Otherwise the second full-price statement is the useful document, because it is the first one showing the true recurring number with no proration in it. Keep it. That figure, rather than the sticker price on anyone's marketing page, is what belongs beside other providers' labels when you decide whether to stay.

And send one email today, before the plan you are leaving disappears from the record: a written request for the archived broadband label for your current plan, citing 47 CFR 8.1(a)(5), which gives them thirty days to produce it.
