Continued billing after in-store cancellation

I am requesting help with incorrect charges on my Xfinity Mobile account.

On April 18, 2026, I visited an Xfinity store in person to cancel my service. I returned my Xfinity equipment, including the gateway/router, and also specifically requested that my mobile service and phone number be cancelled.

I then left the United States on April 19, 2026, so I believed that all of my Xfinity services had been fully terminated before my departure.

However, I recently discovered that I continued to be billed after April 18, and I have now received a notice stating that my Xfinity Mobile service was disconnected due to a past-due balance of $237.94.

Could you please review my account and my April 18 store visit, correct the cancellation date to April 18, remove any charges incurred after that date, and confirm that my account is fully closed?

I would also appreciate confirmation that this incorrect balance will not be sent to a collection agency or negatively affect my credit while this issue is being reviewed.
