Works both way pete, i had a USA seller get me kicked off for a week for unscrupulous buying or somthing, after i had a go at him for his outrages postage charge at check out, this is after i won the item, so i bid and won again with my other account and he did it again and wouldnt post it, then i got a mate to buy it, but he paid with my paypal................. i got owned. he had me removed for a week, emails calls i hit the roof. 14 days late ri had to read and accept the terms and conditions again before they let me back on. LEt me tell you life without Ebay is like cutting off you arse. youll miss it everyday and want it more.
if he is unhappy with the item you can ask that he return it ( and yes they have to pay the postage back) so that usually stops them fussing, and they have to track it ( so they dont black pretend post you) so you get you item back and you fork them off. there are ways to get even. have a mate bid on there cheap shit and reeek hovok with the feedback !!!!!! and also not recieved claims. GEt even i would :O)
