Xbox live account age?

I was making an xbox live account, and i was rushing. So i put my age as 10 when I'm 24. How do i change my age, Or delete the child account,so i can download Mature games or go on face book? I tried going on Xbox.com and editing family setting.I dont want to Wait 8 years, and i dont want to make another one.Xbox live account age?Once you put an age in the account that's it. There is no way to change it. All you can do is make another account. Hopefully you didn't pay for a whole year of xbox live on that account because if you make a new account your gonna have to pay again.Xbox live account age?Wait 8 years.Xbox live account age?There is nothing you can do without contacting Xbox Support. I'm sure if you have some proof of age or I.D of some sort than you could resolve the issue.
