Help! Xbox-Email-Transfer

I just recently got an xbox one and I was going to transfer my acount untillllll............ I figured out the my parents deleted the email that I used! Due to the fact that they send you an confirmation email to make sure it's yours I cant get my account on the Xbox one. I did try to change my email to another on my xbox 360 but it always tells me not at this time. So what should I do? PLEASE HELP!!!
