Incorrect final bill after May 6 cancellation — phone support unable to resolve

I called Xfinity on May 6, 2026 and requested that my service be canceled immediately. However, my account apparently remained active in Xfinity's system after that date, and I continued to be billed.

A $74 payment was subsequently charged despite the cancellation. When I contacted Xfinity, I was instructed by Xfinity to dispute that transaction with my bank. I followed those instructions, but charges/fees related to the returned payment were then added to my account.

My account is now closed, but my August 18 final bill says I owe $173. I have already contacted phone support about the incorrect balance. They told me they could not escalate the issue and that I would need to visit an Xfinity store.

I am formally disputing the $173 final balance. I need Xfinity to review the record of my May 6 cancellation request, correct the effective cancellation date, recalculate my account through that date, remove charges and fees resulting from the subsequent billing/payment dispute, and refund any credit balance that results.
