My account has been hijacked... PLEASE HELP!!

My dad took over my account... You can tell because my dad is very abusive (verbally) he tells players "I hope you get hit by a bus" and "f*ck off" etc.. Everytime I get a bad rating it's because of my dad.
If you look at my game history you can tell because his name is Gary and he talks about his "son" in college and I'm too young to have a "son" in college.
Also Felix Mulvaney has a snap shot from live chat that should "prove" that this is a clear-cut case (pm him, I'm sure that he will send you a copy"
Anyway I could use some help here! OH SHIT!!!! MY DAD JUST WALKED IN!!! GOTTA GO!!!!
