I sold a guitar Amplifier head, after accepting an offer from buyer. I delivered the amp by hand and gave to the buyer. He then wrote on ebay saying he'd received it, was very happy with it and gave me positive feedback. But, because I delivered by hand there was no QR code to scan and ebay is saying the sale is pending, waiting for delivery. The buyer has paid, and the money is showing on my account, but I cant get hold of it, as it says it waiting for delivery.. How do I deal with that? Any advice welcome..thanks
