Credit balance refund not received after service cancellation; moved overseas and cannot call

I canceled my Xfinity Internet service and returned all Comcast-owned equipment on June 4, 2026. My final bill shows a credit balance refund of $23.95, but I have not received the refund in my bank account or any refund selection email from Notifications@refunds.xfinity.com.

I have moved back to Japan, so it is difficult for me to call Xfinity by international phone. I also cannot receive a physical prepaid card at my old service address.

Could someone from Xfinity Support help me confirm the refund status and how I can receive the refund while outside the U.S.?
