Formal Complaint – Ongoing Billing Errors and Overcharges

Dear Xfinity Mobile Customer Service,

I am writing to formally file a complaint regarding repeated and unexplained overcharges on my Xfinity Mobile account. Since activating my current phone line, my monthly bill has changed unpredictably, and I am being charged for an additional line or service that I never authorized.

The issue seems to stem from a claim made by your system that I disconnected a phone line to switch to another carrier. I want to be absolutely clear: I never disconnected any phone line, nor did I transfer my service to another provider. I simply traveled outside the country for a period and did not take the phone with me. I informed customer service of this at the time.

Despite this clarification, I was still charged for a second bill related to a non-existent or mistakenly flagged disconnection. Although I initially made peace with the situation and continued paying to avoid service interruptions, the billing issues have only gotten worse. Each time I make a payment, the next bill is higher without explanation.

This is not only financially burdensome but also highly stressful and unacceptable. I have made multiple attempts to resolve this through your customer service channels without any long-term solution.

I am now demanding the following:

1. A complete investigation and correction of all billing errors.

2. A refund for all wrongful overcharges applied to my account.

3. A clear, written explanation of the charges that have appeared on my account since the issue began.

4. An assurance that the issue is permanently resolved and will not happen again.

If this matter is not resolved within 10 business days, I will be pursuing additional actions, including:

• Filing a formal complaint with the FCC and Better Business Bureau.

• Disputing the charges through my financial institution.

• Considering legal recourse, if necessary.

Please consider this an official billing dispute. I request written acknowledgment of this letter and the steps your team will take to resolve the matter.
