Billing Dispute – Recurring $15 Unreturned Equipment Charges Since April 2026

I need assistance resolving recurring unreturned-equipment charges of $15 per month that I have paid since April 2026.

I am still an active Xfinity internet customer using a replacement modem, but the previous modem was misplaced during our move.

I am requesting a review of the charges already paid, a reasonable one-time resolution for the missing equipment, and permanent removal of the recurring charge.

Due to a disability that makes telephone communication difficult, I am requesting that this matter be handled entirely through written communication.

I have experienced significant difficulties resolving previous billing problems and would appreciate assistance without being required to make another phone call.

Please advise how this can be resolved in writing.
