Incorrect billing charges

I have now spent over SEVEN hours trying to straighten incorrect charges on my Xfinity bill. After visiting my area Xfinity store in Portsmouth, NH, to downgrade service, the trouble began.

I had just moved, transferring my service address. In the chaos of moving, I was billed an odd amount, and paid it. Upon my first of many calls, I was told my bill in fact had incorrect charges. During my next call, I was told I missed paying my June 2025 bill. I have had Comcast for over 30 years, and NEVER missed a payment, and verified my full June 2025 payment was made before the due date.

On my next call, a refund ticket was opened to refund this overpayment. The next day, I received a text from Xfinity saying my ticket was close/no refund.

On my next call (today) I was told I would be credit the amount of the overpayment, but "it won't display on your account." Sure, nothing could go wrong here! If it's not in my account, it's not a refund/credit!

So now, seven hours of useless "customer service," I'm told a supervisor will call me within the next 3 hours. WE'LL SEE

Can someone from this company please fix this mess? I'm pretty sure you're not allowed to extort money from customers.
