Xbox one x gave me a random name (not gamer tag)

I want to know why Microsoft change my gamer tag and gave me a random gamer tag instead of letting me chose my own can someone please explain this to me !!!1

As correctly stated by other members here the 1st free change is only applicable if you have the random name that xbox gave you when you created the account. As it appears you have the gamer tag Elena Velka you have used your first change

Good luck with that. I changed the gamer tag Microsoft gave me to one of MY choosing, which is a name I have been using for other things for decades. Let them try... Besides, I had this "nickname" long before there was an XBox OR a Playstation...

Nope free gamer tag changes can be issued if it is within first 30 days of creation

Xbox support cannot give you a free gamer tag change

It does not matter if your name is in the gamer tag as it is not enough to reset your passwords and since it is not part of your login info unless you have a bad habit of telling everyone that's your name Noone will even guess that

Nor is a forced gamer tag change will satisfy you as you will get a random name

You will have to pay for a change

When you created your account it gave you one free name change. Unfortunately after that you will have to pay to change to a new gamer tag.
