Advice needed really, heres the basic story, not mentioning any names as it may compromise any forthcoming court case... My son bought some really nice trainers, very expensive but rare(is there such a thing?) apparently there is in the world of teenage trainers. He decided to sell for profit on a well known clothing site and was approached by a guy offering the money he wanted. A paypal transaction was duly done and the parcel sent off via special delivery. It was signed for on delivery, now the 'buyer' says he never received it. I notice he is now conveniently selling an identical pair of said trainers, with I presume a fake buying receipt. Paypal have suspended his payment to me, even though it had gone through as I was able to transfer it out of my account. Can they do this?
