Hi fellas, I have this guy who is trying to scam me, he thinks he's smart enough to scam everyone(already did a chargeback on a friend of mine) so I'm looking the way to f*ck him. The method he use is the typical chargeback from paypal. He send the money, get what he wants and then make a chargeback, that's the way he scammed a friend and the way that he's trying to scam me too. What you guys recommend? He's about to send me some money but I don't have idea how to avoid the chargeback. Hope you guys can help me, sorry for my bad english.
