Man that sucks. Sorry your friend got shorted. one time a dealer here was deliberatly shorting people and this one kid called the cops on him anonomously and got him busted. That was kinda low I think, I mean he shoulda just settled things with the dealer on his own and not involved the cops. Anyways if your friend thought the dealer was doing it on purpose then the best way is to not buy from him anymore and pass the word to everyone about him.
