how do i change my xbox username back? i accidentally changed it and it is pissing me off

You would have to go through the same process you did to change it in the first place and choose your old tag, if it's still available.

you need to pay to change it back, yep thats right pay.

I just want to know how you accidentally changed your username!

Hi J11999, my name is Courtney and I would be happy to help.

I'm sorry that you are going through this problem, I want to mention that this is a Microsoft public forum where we are players like you who help other players with basic problems, this means that we are not Microsoft employees.

If on the Minecraft page it says that you have to wait 30 days to change your name again then unfortunately nothing can be done since as we are players we cannot reverse this situation, I would like to be able to help you a little more, but I'm sorry I can't.

I hope you understand, I wish you good luck.

Best regards,
Courtney.

Afraid not.You are responsible for your account & everything that happens on it.

You get one free name change so if you have used that then you will need to pay for another gamertag change.

I'd suggest getting your cousins or their parents to pay for the name change if they were the ones that changed it in the first place.

You should also never let anyone else use your account.
