If you used a credit card - you should have asked your credit card company to do a chargeback. I've only done about 4-5 in my life - and every time the credit card company always went in my favor. One time was even a scammy ebay seller - wouldn't talk to me so I contacted my credit card company told me to send the item back to his address and I would get my money back (the item in question was defective and did not state it in the ebay auction).

Unfortunately some people do abuse it - there was one guy who admitted on DSLreports forums that he uses his credit card to buy all items off ebay. And if he doesn't get it in 2-3 days he does a chargeback - even if he gets the item later. Which, I'm under the impression that when that happens Paypal may yank the funds from the seller's account. I don't agree with it - but I understand why.

My experience with Paypal disputes on the other hand...
