Unexpected subscription charges show up on U.S. statements all the time. It might be a forgotten trial, a renewal you thought you canceled, or a merchant name that doesn't match any app you remember.
Which letter should you send?
Write the company if you can still reach them. Write your card issuer or bank if you want a billing-error claim, not just a support ticket. Those letters do different jobs.
Thing is, phone calls rarely leave a date you can prove. A short letter does. This is general U.S. consumer information, not legal advice for your account.
Sample letters to dispute a subscription charge
Use the first letter when a U.S. credit card was charged. Mail it to the billing-inquiries address printed on your statement. That is often not the payment address.

Re: Billing error notice - account ending [last 4]
Statement date: [date]
Disputed amount: $[amount]
Transaction date: [date]
Merchant: [name as printed]
I am writing to give written notice of a billing error on this account.
The statement dated [date] lists a charge of $[amount] on [date] from [merchant]. I did not make this charge and I did not authorize anyone to make it. I did not agree to a recurring subscription with this merchant.
[If you canceled: I canceled on [date] by [phone, email, or chat]. The charge posted after that.]
Please investigate this as a billing error under the Fair Credit Billing Act and Regulation Z, 12 C.F.R. 1026.13. I am withholding payment of the disputed amount. I ask that you investigate, correct the charge if it is an error, and send written confirmation of your findings. Please do not treat the disputed amount as delinquent while you investigate.
Enclosed is a copy of the statement with the item marked, plus [cancellation email / screenshot / none yet].
You can reach me at [phone] or [email].
Sincerely,
[Your name]Keep the tone flat. Dates and amounts persuade more than anger.
Debit card or ACH works a little differently. You may start with a phone call, then follow it with a letter that cites Regulation E, 12 C.F.R. 1005.11, and describes an error or an unauthorized electronic fund transfer. Ask the bank to investigate.
The company letter is optional and sometimes it gets a faster refund, but it never pauses the issuer's 60-day window.

Re: Cancel and refund - [account email or ID]
Charge of $[amount] on [date]
Please cancel [plan name] immediately and refund $[amount] charged on [date]. [I did not authorize this subscription. / I canceled on [date], and you billed me after that.]
Do not take further payments from [card or bank account ending last 4].
Please confirm the cancellation and refund in writing.
Sincerely,
[Your name]If that statement is already weeks old, send the bank letter first. Email the merchant after.
Credit card, debit, PayPal, or only the merchant
Rights follow the payment rail. They don't follow the logo on the app.
| How you paid | What usually controls | Notice window to treat as real | Where it goes |
|---|---|---|---|
| Credit card | Fair Credit Billing Act and Regulation Z billing-error rules | Written notice generally within 60 days after the issuer sent the statement that first showed the charge | Billing-inquiries address on the statement |
| Debit, ACH, or other EFT | Electronic Fund Transfer Act and Regulation E error procedures | Generally 60 days after the bank sent the statement that first showed the error; oral notice can start the claim | Your bank's error-resolution process |
| PayPal or a similar wallet | The platform's dispute policy, plus any card or bank behind it | Whatever the platform publishes; still watch the card or bank clock | Resolution center, then the funding source if needed |
| Only the merchant | The company's contract and refund practice | Their policy, if they have one | Support, chat, or billing email |
Unauthorized credit-card use is a billing error under that CFPB rule. So is a charge the statement doesn't identify properly. Visa or Mastercard zero-liability language is issuer or network policy, not a substitute for a timely written Regulation Z notice. Ask your issuer how they apply it.
The 60-day deadline and what happens next
For credit cards, the written notice generally must arrive within 60 days after the issuer sent the first statement with the error. That timing lives in the CFPB billing-error regulation. Use the statement's sent date. Don't count from the afternoon you finally opened the app.
The issuer should acknowledge a qualifying notice within 30 days, unless it already corrected the error. The issuer then has two billing cycles, and not more than 90 days, to fix the bill or explain why it believes the charge is valid. You may withhold the disputed amount.
Pay the rest on time. Unpaid undisputed balances can still draw late fees.
Debit sits under Regulation E. Treat that same 60-day statement window as the one that matters. Oral notice can open the claim. Liability for unauthorized transfers can grow if you wait, especially with a lost or stolen access device. A rogue subscription is not always that situation. Report it quickly anyway.
A dispute of last month's debit does not always stop next month's ACH pull. Ask the bank about a stop-payment on that authorization.
Turns out a lot of mystery lines are real firms billing under a corporate name you never saw in the app. Your claim isn't dead just because the descriptor looks odd. Say you didn't authorize that recurring plan. Attach what you have.
How to send the letter
- Pull the statement that first showed the charge and write the 60-day date on it.
- Gather cancellation proof, or a note that you never created an account.
- Fill in the issuer letter. In email or chat, use the last four digits, not the full number.
- Use certified mail, a secure message, or the issuer's dispute form, and save the receipt.
- If you already called, add the call date and reference number.
Attach these when they exist:
- The statement line with merchant name, date, and amount
- A cancellation email, chat log, or in-app screenshot
- A trial-end date or a search showing no account
Missing the signup email is common, so send the notice anyway and let proof follow. A polished packet that arrives late is the weaker move.
This is where people freeze, they can't find the trial email, the statement shows a legal name that looks nothing like the app they opened for five minutes last fall, and they start thinking a clerk will wave them off while another cycle is already sitting in the merchant's queue. Get the letter out. Keep hunting in spam after.
If the issuer denies it
A billing-error letter is the federal process with your issuer. A chargeback is the card-network process the bank often starts once you dispute the transaction. You don't need a magic chargeback phrase. You need the date, the amount, the merchant as printed, and why it wasn't authorized.
PayPal is a separate track, so open their dispute if that's how you paid. If a credit or debit card funded it, watch that card's window too. The two clocks are not synced.
If they finish against you, ask for the documents they used. A complaint to the Consumer Financial Protection Bureau is a later step that can trigger another review, not a promised refund. Use it if the issuer closed the claim.
Stop the subscription in writing even after a dispute, because the next pull can hit a new card.
To be honest, people lose these by waiting on a chat agent while the 60-day window runs out. Send the letter first.
Grab tonight's statement and mark the 60-day date. Get the issuer notice out this week, and tell the company in writing to cancel and stop billing.
