Horrible service especially being a part of Comcast since 1994

I am extremely frustrated and exhausted from repeatedly trying to resolve this matter through messages and chats. I am formally requesting that Xfinity stop charging me incorrectly and immediately address the money that is owed back to me.

I upgraded to the iPhone 17 Pro Max based on the promotion that was advertised. The terms presented at the time of upgrade have not been honored as represented. What was marketed as a promotional offer does not align with what I am being billed, and that is unacceptable.

This feels misleading and deceptive. I entered into this upgrade based on the understanding that specific promotional credits and pricing would apply. If those terms are not being honored, then I expect:

1. A full explanation in writing of the charges.
2. Immediate correction of any billing errors.
3. Reimbursement or account credit for any overcharges.

I will no longer continue back-and-forth messaging. From this point forward, I expect communication via email and a direct phone call from a qualified representative who has the authority to resolve this issue.

I have been a customer for many years, and this situation should not require this level of effort to correct. Please treat this as a formal billing dispute and respond accordingly.
