Changing child account to adult account

I made xbox account years ago for Minecraft. But I didn't have much interest in realms back then. Now when I check it, it says my account is child account and can't play realms, and I need an adult account to promote me to child account. I made this account
alone. And none of my parents or old relatives don't have xbox account. What am I supposed to do?

Adult to child Account

How do we change an adult account to a child account. We tried changing the birthdate, but it still says it is an adult account.

Changing the birthdate under the profile doesn't changes a child account into adult account

 

Hello, hopefully this helps. If not I recommend contacting Xbox support.
