Moved to a new address months ago and switched to using wife's Xfinity account, but my service/charges at the old address never cancelled.

Hello! We moved to a new home in April 2024 and began using my wife's Xfinity account for internet services at the new address (and we're still/currently customers under her account), but the service, which included the add-on for unlimited data, at our old address (that we no longer own) continued to charge the full monthly service charge to our bank account each month despite no one using the service. I've recently been laid off of work and noticed the recurring charges while looking for ways to reduce our monthly costs during my job search. I've since called Xfinity and cancelled/disconnected the internet service for the old address, but is there any way we can please have these monthly charges refunded to our account given that no service was used? Thanks so much for your help in advance!
