Problem with my age

Hey there Jeffray thanks for keeping in touch.

Sure thing instead of Requesting the Callback, select Message with an Xbox Gamer. Give it a shot and let us know how it goes!

If you have registered an account in xbox live service as child account you can't change that by changing the birthdate under your profile data. Once the servers register your account as under 18+ they will calculate the years it remains for your account
to be upgraded.

Unfortunately there is no way to change a child account to an adult account as it goes by the original birthdate you put in while making the account.

If my answer helped please remember to mark as an answer or upvote as helpful, please and thank you

I don't know how to talk to an agent they always put me at the begining

If your birthday is correct and you verified your an adult through the verifications process it should classify you as an adult. The only other reason I can think of is your account is linked into a family account as a child or sub account. If this is
the case then it does not matter your age you will always be classified as a child. I would try and reach our to Microsoft's support at https://support.xbox.com/en-US/ to see if they can resolve your account problem
