Refunding app with a Pre-Paid Visa card.

I just refunded an app that I had downloaded on accident, however the purchase was made using a non-reloadable prepaid Visa gift card. The refund was accepted and the website said, the purchase was going to be refunded through the original payment method. However, the card is non-reloadable, meaning you can’t add money to it. I assumed they were going to give me compensation in apple credit. I know it says allow up to 30-60 days for the funds to process, but assuming they did refund through the original payment method, I’m never going to get the money. So what should I do from here?
