You can't. VM don't permit this. You have two choices. First get your son to cancel the account formally - he needs to give 30 days notice. The you can apply for a new account in your name. Second you can tell VM that your son has moved out (gone away) and VM will close his account and in time allow you to apply for a new one in your name. The fact that you pay the bills is irrelevant. You are not the account holder.
