I just wanted to buy the Xbox Game Pass with my father and now it says that I have to have permission from my parents? - 1

How can you confirm that? We also don't get an email where you can confirm this. Here I get this message

If your father doesn't get an email, he should call support.

He can be reached today until 5:30 p.m.

This is certainly due to your data protection / parental control settings which do not allow such a purchase.

To change this you should ask your parents because they have set your account that way.
