refund Support

I moved from DE to PA (temporary) to Bel Air, MD. I was owed an Xfinity refund of $222.88 from DE. In 1/2026 I received an Xfinity Debit Card for the $222.88, but the card Expired in 11/25. I've made 10 calls & 2 store visits to resolve this issue. I am told that the "Finance Team" has declined to reissue the refund due to me. I've contacted FCC  & BBB today. What can I do???
