I was signing up for a Battle.net account and since I was underage they asked for my parents' email. I entered my father's email. The problem is he was making a Battle.net account the very next day the email does not seem to work. He assumes it was because his email is linked to my account. Is there a way to change the parent email linked to my account? I don't want to terminate the account because I'm using a guest pass for Diablo and I have activated everything.
