My microsoft account not giving my gamer tag option

So i found out that when i used my skype account linking the minecraft ps4 account microsoft made a gamer tag for me and once i realized this i just went ahead and changed it. I assumed it would use my playstation gamer tag . It didnt tell me that it would
be making one for me and it didnt even give me the option at the time to make my own. So once i logged into the microsoft account and looked at the xbox account stuff there was the odd gamer tag

I am not sure how it happened. I already had a Microsoft account. When I got my xbox I created an account and got a gamer tag while setting up my xbox. I signed up for xbox live from my xbox using my existing gamer tag and Microsoft account. I then went
to xbox live and signed in using my Miicrosoft account, and for some reason when I did this a new gamer tag was created and associate to my Microsoft account. So, now when I log into xbox live I see one gamer tag. But on my xbox I have a different gamer
tag.

Under settings, then account , all options that show something with a name show my old gamer tag, I could not find any account option under the settings, and then system option but when I play a game then it shows my new gamer tag, iv only just finished downloading a game to play, I don't understand why I still have to see my old gamer tag on everything else though

The account of my xbox dissapear and my gamer tag too:I open my xbox and it was like I just bought it. No account no gamer tag and microsoft account don t exist anymore too

You'll see a new gamer tag like that when you sign in with a new account. Since you stated that there are no games or gamer score, that's another indication that you've signed in with the wrong sign in email address that's not associated with the Neo gamer
tag.

You can contact Xbox Support and give them your gamer tag and they will send out a security/verification code to the phone/email you have setup on your account. Without that code, they won't be able to see your account info.
