Not sure. I try to avoid phony people on PayPal.
Did you take pictures/evidence? As long as the buyer received the item, there should be no reason for the chargeback to go through.
Well it was not my but my friend.
Yes, he took few screenshots (like 4-5) and send them to paypal.
Now he's waiting for them to say something.
At the moment it says "closed" on paypal [after 3 weeks of waiting]
I have no experience on what to do, sorry. However, I suggest asking a mod to move your thread here http://sythe.org/forumdisplay.php?f=295 so you can get better responses.
