Billing and lack of support

I am writing to formally express my dissatisfaction with the lack of customer care I have experienced regarding my accounts and billing issues.

I initially contacted Xfinity to request a refund for charges applied to an account that has been closed. In addition, I was billed for services on an account that should not have had any active service. Despite my clear requests, I was transferred between multiple agents without receiving meaningful assistance. To make matters worse, I was informed that my bill would be increasing, yet no explanation was provided for this change.

This experience has left me with unresolved issues, unnecessary frustration, and no clarity about why I am being billed incorrectly. I expect the following to be addressed promptly:

1. A full review and refund for any charges made to the closed account. $160
2. A correction and refund of charges for the account that should not have had service.
3. A clear explanation of why I was told my bill would be increasing.
4. Confirmation that my accounts are accurately updated and reflect only the services I have authorized.

I trust Xfinity values its customers and will treat this matter with urgency. Please provide a written response with a clear resolution timeline.
