We are trying to clarify a unique situation we have with refunds.
For purchases using a card (debit or credit) Shopify only allows refunds back to the original card used for purchase aka the card on file. What happens if that original card used for purchase has since expired/become invalid since the customer made the purchase and then requests a refund? The most common scenario we are facing is that the original payment card has expired and the customer has received a new card (with new numbers) but the bank account associated with the old card is the same bank account associate with the new card. So the customers bank account has stayed the same, but the card number associated with that bank account is now different from what we have on file. Since we can only refund back to the original card used for purchase, we would be refunding to an expired card. Will the customer still receive these funds since the bank account is still the same? What are our options when this happens?
