How do you link 2 xbox gamertags to 1 xbox dot com account because i linked the wrong gamertag to my acc and i need the right gamertag to link it to bungie acc?

To link the correct Xbox gamertag to your Xbox.com account, you'll need to first unlink the incorrect gamertag. Sign in to your Xbox account, go to "Profile," and select the option to manage linked accounts. After unlinking, you can sign out and then sign in with the correct Xbox gamertag you wish to link. Finally, ensure that your Bungie account is linked to the correct gamertag by following their account linking process.
