I sold an item of clothing last week to a buyer whose here offers I'd refused in the basis that I don't ship to Africa. They had zero feedback. They went ahead and bought the item anyway, but I cancelled it and as they'd not paid it was no problem. However, they've paid today,mand the paypal address is to an address in London. This makes me very uneasy. How were they able to pay at all when the transaction was cancelled? Am I ok to simply refund? Or is this some kind of huge scam? I'm at a loss what to do.
