Someone changed my username on my Xbox account awhile back how could I change it for free?

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello Xqnak, unfortunately it is not possible, the entire Gamertag exchange system is automatic in the system, after the first free exchange is made it will charge for the next exchanges.

Same exact thing here brother, hadn't touched my account in awhile, only to come back to a changed password, username, and a cringy skin. just found out I could get it for free on windows last week, as I've had Java since '15 as well, and lone behold,
it was stolen just last month.

I'm Samy an independent advisor. Welcome to the community. How are you?

Can I change my username?

Users who have a Mojang account or a Microsoft account can change their username for free at www.minecraft.net/en-us/profile. Click Change next to your profile name.

If you have an older account and you sign in with your username, you need to migrate to a Mojang account before you can change your username. Minecraft support is unable to assist with changing usernames as system is set up to be self-service.

How often can I change my username?

You can change your username once every 30 days. When you change your username, your previous name is saved for 37 days. This gives you an additional week to change back if you change your mind before your previous username becomes available to anyone else.

Apparently someone's been getting on my Xbox account and setting their Xbox as my home Xbox, I've purchased multiple games alone and multiple add on to just released games. I'd rather not have a free loader or a complete stranger have access to my account.
I've already changed my password and username but that hasn't stopped them. I'm unable to change it back to my home Xbox because they've already change sit back twice and me once.

When i logged onto my account someone changed it to plxiity my origanal was troller and it costed me 14 dollars so if i can get my money back and you change my username back to troller8403 then thank you.
