Unauthorized payment

After tons of problems with xfinity mobile I decided to cancel services in Jan 2026.I had an automatic payment coming later that month and fine I left my card on file and paid.

next day I call to have them remove the card on file because it was not letting me do it in the app. The agent removed it. I told them that I am not authorizing any future payments.The agent said that it will not happen. Then February 21 came and they are charging me $900 For a remainder of phone charges. I clearly told them that I did not authorized this payment. I called and they said they cannot do anything about it. I told them that it should be illegal. They are using my card without authorization. Even the guy I spoke to today said that he couldn’t see my card. How could they do this. I’m going to try to cancel the payment with my bank, but the problem is they still have that card somewhere in their system.

This adds to the terrible customer service they have.
