Hey there, you should try the Forgot My Password feature on Live.com

I've recovered the gamertag of the parent account before and it worked fine but nothing happened and my problem is still there ,have there been any known issues with this before ? It seems to be a fault in the settings

Sign out of any profile on the console, then on the list of Gamertags, scroll right until you find the "Recover" option. Select this and follow the prompts. You'll need the account WLID and password.

There is a 4-digit passcode that is used on the Parent Account to prevent access to the settings, but when it asks you to "log in" with the parent account, it's asking for the WLID/Password of the account itself. This can be tested by having the parent recover
his/her account with this same info. If it doesn't work to recover, it isn't correct, and they should call phone support to recover their information. (support.xbox.com/.../contact-us.aspx)
