Unauthorized Mobile Line Charges - Immediate Action Required

Dear Xfinity Mobile Customer Service,

I am writing to formally dispute unauthorized mobile line charges on my account and demand an immediate resolution.

Account Details:

• Account Holder: [Edited: "Personal Information"]
• Account Number: [Edited: "Personal Information"]
• Account Email: [Edited: "Personal Information"]

I terminated my Xfinity internet service in November 2024 and explicitly did not activate any mobile service. During a recent customer service call, a representative confirmed that I do not have an active mobile service line and canceled a previous incorrect charge of $9.09 on February 15th.

Despite this confirmation, Xfinity Mobile continues to bill me for a mobile line that was never opened or utilized. I categorically deny authorizing this service and demand the following immediate actions:

1. Conduct a thorough review of my account
2. Terminate the unauthorized mobile line
3. Immediately cease all billing related to this unauthorized service
4. Provide a complete refund of all charges associated with this unauthorized line
5. Send written confirmation of account resolution

LEGAL NOTICE: If this matter is not resolved within 10 business days, I am prepared to pursue all available legal remedies, including but not limited to filing a complaint with:

• California Public Utilities Commission
• Federal Communications Commission (FCC)
• Small Claims Court
• Initiating legal action to recover unauthorized charges, potential damages, and legal costs

I expect a prompt and comprehensive written response detailing the steps you will take to resolve this issue.

Sincerely, 

[Edited: "Personal Information"]
