Dude just call up sony and tell them that your friend brought someone and that person was on your system and they went on your account and changed the email and pass and then deleted the account off your system and now they will not give it back. Or something like that and then they will transfer you to the account department then just tell the story again and they will reset the stuff back and then u got your account back. Just remember to change the email and pass so that the fag cant recover the account. and also if the guy or girl ask "did u get a email conformation for the account change" just tell them that you used a old email and you dont have access to it anymore.

I had to do this when someone tried to take my account without paying

tried it and it didnt work im pissed oh well now my goal is to get a 360 i can probably get one for free by trading in games and old ps3
