An automatic payment dispute letter is a formal written request sent to your bank asking them to investigate and reverse an unauthorized or incorrect recurring charge (ACH debit) from a merchant. When a merchant debits your account without your consent, for the wrong amount, or after you’ve already cancelled the service, a written dispute creates a documented paper trail that a phone call alone cannot provide.
Under Regulation E, consumers have the right to dispute unauthorized electronic fund transfers. A written dispute letter timestamps your notification, identifies the specific transaction, and puts the bank on notice to investigate. If the charge is found to be unauthorized, the bank must credit the disputed amount back to your account, typically within 10 business days of receiving your claim.

My gym kept billing me three months after I cancelled in person. I sent this letter to my bank and they reversed all three charges within two weeks. Having the letter on file made the process straightforward.

Signed up for a free trial that auto-converted to $49.99/month with no clear warning. Couldn’t reach the company by phone. This letter got my bank to investigate and I had a provisional credit in my account within a week.
Kevin T.
A streaming service double-charged me and customer support was useless. Generated this letter in five minutes, walked it into my branch, and the duplicate charge was reversed. The banker said a written dispute makes their job easier.

An automatic payment dispute letter is a formal request sent to your bank asking them to investigate and reverse an unauthorized or incorrect ACH debit from a merchant. It creates a written record of your dispute with a specific date, transaction details, and your request for a reversal — stronger evidence than a phone call if the issue escalates.
Under Regulation E, you generally have 60 days from the date the unauthorized transaction appears on your bank statement to report it. After 60 days, the bank may not be required to investigate or refund the charge. Act as soon as you notice a problem.
Your bank must acknowledge the dispute and begin an investigation, typically within 10 business days. During the investigation, many banks will issue a provisional credit for the disputed amount. If the bank determines the charge was unauthorized, the credit becomes permanent. If not, they must explain their findings in writing.
Yes. While your bank handles the formal dispute, contacting the merchant to cancel the recurring payment and request a refund can resolve the issue faster. Keep records of all communication with the merchant — emails, chat transcripts, cancellation confirmation numbers — in case your bank asks for supporting documentation.
No. This letter disputes an ACH debit (automatic bank withdrawal), which is governed by Regulation E and NACHA rules. Credit card chargebacks are governed by Regulation Z and the card network’s rules. The process and timelines differ, but the goal is the same: reversing an unauthorized charge.
Yes. In addition to disputing the past charge, you can request a stop payment on future debits from the same merchant. Many banks offer an ACH block or filter that prevents a specific originator from debiting your account. You can also revoke authorization directly with the merchant in writing.
