PayPal finale Part 2

As I said before, PayPal sucks....today has been interesting. After the payment was reversed I filed a non-paying bidder claim with eBay to try and get my fees back. The buyer responded that he had already paid and thought I was trying to get paid twice - he seemed to have no idea that PayPal had reversed the transaction. Once he figured this out he immediately paid me again. So it seems that PayPal reversed the transaction all on their own, with no feedback from the buyer. Has anyone ever heard of this before? I have emailed PayPal to try and get more information. The good news is I have the money again.
