Ugh. Finally. For the past two months PayPal has been up my butt. In March I sold my old iMac (Graphite SE) to this woman through eBay. Two months ago I get an e-mail from PayPal saying that the transaction is being disputed, and that I need to provide a tracking number or something along those lines to prove that I had sent it, otherwise they would initiate the chargeback process. Well, seeing as how five months had gone by without a problem, I'd thrown it away, so I had no way to prove I'd sent it. I sent a rather nasty e-mail to the woman I sold it to, and she responded all confusedly - she hadn't disputed anything. I called PayPal - they said they couldn't give me anymore information. So now, after about 500 emails and phone calls between me, PayPal, eBay, this woman, her credit card company, and UPS, they've finally stopped the whole thing, but only after the chargeback had already been processed, and about a hundred dollars in fees had been charged to my account. They really piss me off. Has anybody else had similar experiences?
