In a family I've never seen and can't leave to join real one

I just bought a Xbox gift card but can't use it because I'm on a child account and I looked at the family and I'm in a family with the gamer tag TarryLive339436 which I've never seen and I can't leave to join my real family so I can use the gift card and
way I can leave the family?

Can't join an Xbox One family

I recently bought an Xbox One and found out I had restrictions because my account was registered as a teens account. To change this I tried to join a family with an adult account which would be able to change my settings, however, I can't join a family because
I'm already part of one, even though I don't know the account who's family I am part of. Because I'm not an adult account I can't leave the family, so I'm stuck in a random family with an account that doesn't belong to anyone. Is there anything I can do to
leave this family?

 

Can't leave family

Hi there,

This particular feature doesn't require access to the e-mail account itself. The account can still be logged into on our
account page. But ngocphi is correct that your stepfathers account would need to be accessed to change this features settings. Happy gaming!

 

The parent account has to release your child account so that i can joined into your correct family.
