Straight up scammer and liar

He scammed a guy(OmgItsYourMom) off an account and sold me the account. The original owner made a post about how his account got taken away and that somebody changed the password. The original owner's name is Michael, I asked Dollar who he got the account from and he told me from a guy named Michael. Before I knew that, I asked for the info to the account, so that it could be 100% mine, as he changed the password on me once already after purchase. He said he doesn't know the info, but in order to change the password you need the security questions, which I asked for and he said he didn't know. He's the one who changed them and scammed the original owner of the account...plain and simple and now he wants to ignore me...smh
