Tips for cancelling AT&T Internet by phone

  • Have the account number and the account holder's details in front of you. Many companies only cancel when they're talking to the account holder.
  • Say you want to cancel in your first sentence. You can turn down retention offers without giving a reason.
  • Ask for a cancellation confirmation number and the exact date service and billing end.
  • Write down the date and time of the call and the name of the person you spoke with.
  • Ask them to email the confirmation, then check that it arrives.
  • Check your next statement to make sure the charges stopped.

If you'd rather not make the call, send us a request. We call the company, handle the hold and the retention offers, and email you the confirmation. You pay $29 only after the cancellation is confirmed.

If AT&T Internet keeps charging you after you cancel

Check the dates first. A charge that covers your notice period or the last billing cycle may be allowed by your contract. A charge for a period after your cancellation date usually isn't.

  1. Contact the company in writing. Say when you cancelled and how, and ask them to refund every charge after your cancellation date. Include your proof.
  2. If they don't fix it, dispute the charge with your bank or card issuer. Give the cancellation date and send the proof: a copy of your letter and the USPS delivery record, or the confirmation number from your call.
  3. If charges keep coming, ask your bank whether it can block future payments to that company.
  4. File a complaint with your state attorney general's consumer protection office. It creates a record, and some companies respond faster once one is filed.

Banks and card issuers set deadlines for disputes, usually counted from the statement date. Don't wait for several months of charges to pile up before you act.
