3 weeks ago i sold a XX4 to the USA and the guy paid immediately, the day after i got a message from paypal stating 'the buyer or the buyers bank have reversed the payment', anyway to cut a long story short after the guy had taken out a resolution case it turns out that paypal froze the funds initially for no apparent reason

they still however investigated the case (which they caused

) and found in favour of the buyer even though i provided them with a scanned copy of postage receipt including address it was sent to, date, cost, tracking number, weight and signature, and they have given him his money back!
However, i have been in regular contact with the guy who's a racer and seems spot on, so when the package arrives with him i/we will be rocketing paypal big time about all the agro, and the incomprehensible fact that they found in favour of the buyer for a dispute they caused and even though all aspects from both sides had been proved - They basically argued against themsleves and found me at fault

.
In summary paypals and ebays resolution centres are far from perfect, and in my case they were totally inept.
