Xfinity has Been taking my money for a year

I was a customer with Xfinity between between January 2022 and December 2023; I changed addresses in January of 2023 I spoke to an online representative to have my accounts address transferred to the new address as Xfinity was the only ISP that covered the new location. After about 2 hours of assuring the representative I did not want new equipment and just wanted the address changed so I could get internet at the new place. They said it would be handled.

1 week later I was sent new equipment anyways. I didn't think anything of it and returned the old equipment. I no longer had access to the old account so I figured the transfer was done LITTLE DID I KNOW. They continue to charge me for the old account. Autopay was still enabled and I had no way to turn it off. I did not notice this until after I moved again in December of 2023 and continued to be charged after I closed my account. The original address was still being charged and had been for the entire year via autopay.

I had the account closed and was told I would be receiving a refund on February 13th when the next billing cycle processed for the ENTIRE YEAR I was being charged for an address I did not live at and returned the equipment for. Now it is February 14th and I'm being told its my fault for not noticing. I went to a physical store and was given a number to call to file a claim, however my account number doesn't exist to the automated system so I can't even call somebody. to make a claim.

This isn't a small amount of money to me its around 1300 dollars. and it is ridiculous that you as a company can continue to take my money after I've returned your equipment FOR AN ENTIRE YEAR and than blame me for the issue after I WENT THROUGH AN ACTUAL PERSON to have my address transferred.
