Bill and payment

Hello, I am a longtime Xfinity in Mobile customer, and I need to file a formal complaint about my iPhone upgrade and billing.  I upgraded from an iPhone 16 to an iPhone 17, but I am still being charged for both phones. I have contacted Xfinity every month to try to resolve this issue. Each time, I have had to spend about an hour on the phone explaining the same problem, but it has still not been resolved. This situation has become very frustrating and has also affected my work because of the amount of time I have had to spend calling Xfinity.I also went to an Xfinity store in person, but they told me they could not help because I purchased the phone online.

I am requesting that this issue be escalated to a supervisor or the appropriate billing/Device Trade-In department. Please review my account, correct the billing, and refund any incorrect charges that I have paid.

Please provide me with a case or ticket number and a written explanation of how this issue will be resolved.
