Yesterday I said I hadn't had any problems but a problem has now come to light and paypal have been useless at helping me. Normally payments are instantaneous but the last payment I tried to make seems to have gone through as an echeque instead - it is still showing as pending/uncleared after a week and says it won't be cleared for another week. The seller is getting nervous about his prospects of getting his money and it may affect my ebay feedback rating.
So paypal is fine ...until you have a problem.
