I just had a crazy theory, what if he sold it to you because his parents put the parental control on it so now he can buy a new wii without his parents knowing! And now he's gonna say that he didn't put parental controls on it! I know it's crazy but that might just be the reason. If you still can't get the parental controls off tell Nintendo that it shipped with them...lol..and they might send you a new one. good luck!
