you can file a police report in his city and they'll send a detective to his house. That's what I did when someone tried to scam me on here and it scared the guy poopless. I got my money back needless to say. Just have all PMs and pages about the sale printed out because they'll want you to fax the info of the transaction to them.
BTW Headbussaboi seems like a cool guy, kinda weird that this happened. I hope it all works out. Worse comes to worse, ROADTRIP
