I sold a coat on Ebay, 3 weeks ago, sent it by recorded delivery, the buyer then contacts me to say the coat is not as described and wants a full refund. It was stated in the listing, all the little faults I could find and to say it was USED, the coat as lovely, completely fine in my opinion , but there we are. So I contact them to say fine, I will refund once the coat has been returned to me by recorded delivery, 2 weeks later, no coat has arrived but they are e-mailing asking why I have not refunded them yet as the coat has been delivered, it has not been delivered back to me, I have asked them for the tracker number on the receipt but they have said they have lost the receipt, what do I do, I am fuming, Ebay are not being helpful, the last e-mail from the buyer has said I have until Monday to refund, or else they will take out a dispute
