If a collector's ACH debit exceeds the amount you approved, treat the extra dollars as unauthorized and act the same day. Call your bank to dispute the excess, then follow up in writing and revoke the collector's debit permission. An ACH debit is an electronic pull from your checking account using your routing and account numbers. Collectors often use one-time or recurring authorizations, and any amount above the agreed figure needs separate permission.

What did you actually authorize?
Pull your proof before you call anyone. Look for the signed form, online agreement, email, or call notes showing the exact amount, date, and frequency you allowed.
Compare that record to your bank statement. A $200 agreed payment that posts as $475 is a clear overcharge, while a recurring agreement may allow fees you missed.
What should you ask your bank to do?
Call the number for disputes or unauthorized transactions, not general customer service. Say the debit exceeded your written authorization and ask about disputing the excess, stopping future debits from that originator, and reversing any overdraft fee.
File the written follow-up the same day. Keep screenshots of the authorization, statement, and confirmation.
- State the authorized amount, posted amount, date, and collector name
- Ask what written dispute form or affidavit the bank requires
- Ask whether a stop payment, block, or new account number fits your case
- Request written confirmation and a claim number
How do you cut off the collector?
Send the collector a short written revocation. State that you cancel ACH authorization for that account, list the account and the original authorized amount, and require future contact in writing.
Send a copy to your bank and keep proof of delivery. Do not rely on a phone cancellation alone. If you still owe the debt, state how you will pay instead, such as by money order or one-time bill pay you control.
How does this affect your bonus and balance?
An oversized debit can trigger overdraft fees, drop you below a minimum balance, or interrupt a qualifying direct deposit. Those problems can delay or disqualify a sign-up bonus.
Move bonus-qualifying deposits and bill payments apart when possible. Turn on low-balance alerts, keep a small buffer in an account used for collector payments, and avoid closing an account while a bonus or dispute is pending.
When should you escalate?
Escalate if the bank denies the dispute, the collector pulls again after revocation, or fees remain. Ask the bank for a supervisor review and submit the authorization proof a second time.
You can also file a complaint with your state financial regulator or a federal consumer agency. Keep a one-page timeline with dates, names, amounts, and copies of every letter and form until the dispute closes.
Frequently Asked Questions
Does revoking ACH permission erase the debt?
No. It only stops electronic pulls from that account. The collector can still bill you another way.
Should you close the checking account?
Closing can work, but it may disrupt direct deposits tied to a bonus. Ask your bank first about a block or new account number.
