Unauthorized Mobile Line and Billing Dispute

I am requesting an investigation into an unauthorized mobile number that was added to my Xfinity account without my knowledge or permission.

[Edited: "Personal Information”]

I have been making my payments through the Xfinity app. Yesterday, I chose the option to receive/view my statement online, and after reviewing the actual statement, I discovered that the phone number [Edited: "Personal Information”] was listed on my account. I did not authorize this number to be added to my account, and this number does not belong to me or anyone I authorized.

I have been paying additional charges associated with this unauthorized line without realizing what the charges were for because I had been paying directly through the app rather than reviewing the detailed statement.

I am requesting that Xfinity investigate when and how this number was added to my account, provide any available information showing how it was authorized, remove the unauthorized number, and refund all charges I have paid that are associated with this line.

Please escalate this matter to the appropriate billing and/or fraud department and provide me with a case or reference number for my records.
