Billing

I canceled my service last year on Jan 7, 2025. A of match i have had a charge off account with Xfinity with the representatives telling me it's due to early termination of service and unreturned equipment. When I canceled service I went in person to return my equipment and pay all charges. I was told I that I was good as far a equipment but the final bill would come after a couple days. Jan 13, 2025, I spoke to someone over the phone and paid the final charges and told that I was complete. I have called the customer service line maybe 3 times each week the last few weeks trying to talk to someone and get updates on why I'm being charged and when they can remove it. I should not be getting charged period. Even if it were just an early termination fee, I left due to military necessity and have orders to prove it but no one will accept them. I'm currently nowhere near an Xfinity location abs trying to do all this virtually. I need this resolved because I'm getting close to being done trying to handle this with yall directly and going through a 3rd party legal service. This $347 charge off is wrongfully on my credit.
