my order was canceled and the iphone 17 pro max returned and I never received my money back

I ordered 2 iPhone 17 Pro Max, I tried to contact more than 30 times to try to change the address on my account because the registered address is on the street inside my condominium and there is no shipping service on that street in the United States. This was not resolved so the phones did not arrive at my house and it was returned to xfinity and arrived on October 31st. Then I received an email saying the order was canceled but I never got my money back. I made more than 50 calls to Xfinity and tickets were opened (ECM0017805619 - ecm1611200189) which were closed without any resolution. I called my bank and opened a complaint to get my money back and the bank told me that they are trying to contact xfinity and have not had any response yet and so it is not possible to refund my money and that only xfinity can resolve this. I don't understand how difficult it is for my money to be refunded if you have the information that the iPhone was returned to you.
