Billing Dispute for Unexpected Charges Following Promotional Rate

Whom It May Concern:

I am writing to formally dispute the charges on my Xfinity account following an unexpected increase in my monthly bill.

I had been paying $40.00 per month for my Xfinity service. Without any prior understanding that my bill would increase so significantly, my monthly charge rose to $120.00. When I contacted Xfinity Customer Service, I was informed that the $40.00 monthly rate had been a promotional price and that the promotion had ended.

I explained that the increase was excessive and requested to speak with a supervisor to discuss possible billing adjustments or alternative options. My request was denied, and I was told that I had no options other than paying the higher amount.

Because I was unable to resolve the issue through customer service, I canceled my service and returned all Xfinity equipment immediately.

I respectfully request that Xfinity review my account and remove or adjust any disputed charges resulting from this unexpected rate increase. I also ask that you provide a detailed explanation of the charges and confirm that my account reflects the timely return of all equipment so that no additional fees are assessed.

Please investigate this matter and respond to me in writing with the results of your review. I appreciate your prompt attention to resolving this billing dispute fairly.
