actually paypal requires solid written proof if you have to win a case with them. I got screwed up for $20 once when a user donated and asked again to be sent back after 20 odd days and I didn't even remember if he had donated to me paypal sucks in disputes
Phone them and also he should not get away with it as its virtual items, later on they will just tell that person its closed because they don't really support online trading!
thanks Not really in this case, as this is Digital item.I think u qualify for that too but i am not sure if the policy applies to donations.
