My nametag is changing back to its old one

If you did the change on the official Xbox website, you may need to download the profile fresh to your Xbox. Clear it from your console then login again.

I apologize if this was vague, there was originally one xbox nametag associated with the microsoft account, this one held my purchased instance of minecraft. One day it prompted me to enter a nametag, I entered it, and a new nametag was created that didn't have the instance of minecraft purchased. I cannot access the original nametag and it keeps prompting me to purchase minecraft.

Hi GOLOSOVOY,

Thanks for keeping us updated with your replies. As stated previously by our Ambassadors, you may

change your Gamertag at any time; however, if this is not your first change, then you would need to pay for the change. Based on the error message you're getting when you attempt to claim your preferred Gamertag, it seems that that Gamertag has already
been claimed, so you would need to choose something different, or make a variation of the preferred name. In this case, if you only wish to make all the letters capitalized, then since it is of the same spelling, that Gamertag is already in use by yourself.

As all possible answers have been provided and to prevent repetitive answers as well, we'll be locking this thread at this time.
If you have any further questions or concerns feel free to come back to the Xbox forums.

Thank you and have a great day!

"You can easily change your Xbox gamertag. If your gamertag was created for you when you initially signed up for Xbox (meaning you did not choose it yourself), you can change it one time for free. Additional
Xbox gamertag changes cost extra."

"If you created your own gamertag at signup and want to change it, you will be charged (fee varies by region and currency)."

Realy? It's a bad news..

No another way?..
