So I sold a item on swappa but I can’t fulfill the purchase and the guy already made a transaction to my account. I tried to issue a refund but for some reason it would say refund unavailable for some reason. It won’t let me refund him and I don’t know why?
Do you have a linked and confirmed bank account on your paypal account (not debit card)?
Only if you only have the money the buyer sent you and you want to refund then there won't be enough as paypal do not return the fee you were charged when your buyer paid as part of any refund that you issue.
So you would need to add the fee amount to the balance OR fund the refund from a linked bank account.
