Gain access to GamerTag

Hmm? You wouldn't add a gamertag. The purchasing account automatically gains access to the content via a Live login. Any other gamertag can access it from the Home Console only.

You cannot use this gamertag as it is used on another Microsoft Account required service.

You can claim trademark as much as you please, but you're never going to gain access to that gamertag.

This is an older thread. For future reference it would be better to create a new one detailing your issue.

If you have lost access to your gamertag then contact phone support and open an Unauthorized Access Ticket for the gamertag.

Also, no one can hack your gamertag. The only way to gain access is if you gave out your log in info or were phished for it.

Finally, please do not name and shame on the forums. Thank you.

Please note that disputing charges would result in the account being suspended, potentially making the chances of recovering it in the future impossible.
