Comcast Business Mobile: 30-month billing error after cancellation request — need official review

Hello Xfinity/Comcast Support Team,

I’m hoping someone from Xfinity/Comcast Business Support can help review a long-standing billing issue.

Account details (high level):

• Comcast Business Mobile line opened: July 2023
• No contract
• No device
• Line was never used

I emailed my Comcast representative in July 2023 requesting removal of the mobile line, but the line was never canceled on Comcast’s end. As a result, I was billed from July 2023 through December 2025 — approximately 30 months at $45/month ($1,350) for unused service.

I have:

• Contacted Comcast Business support
• Been routed to the Loyalty/Retention team
• Requested cancellation (now pending/confirmed)
• Submitted an escalation to Executive Customer Relations

I am requesting:

1. Written confirmation that the mobile line is fully canceled
2. A retroactive billing credit for the unused service billed after my cancellation request

This appears to be a billing error, not a usage dispute, and I’m seeking a fair resolution.

If an official Xfinity/Comcast representative is available here, I’d appreciate guidance on next steps or assistance reviewing this account.

Thank you.
