someone logged into my account and changed the username on it and i want to revert it back...

i already have access to the account i just want to revert the username that they changed without paying for it

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.

my account was logged into and my username "vkpu" was changed and now is up for sale on Instagram is there anyway i can get my username back? i don't know why someone would hack my account to steal the name

sadly miscreants galore mess with peoples accounts all the time

Go ahead and try Calling up Microsoft on the phone 1-877-696-7786. And Ask them to revert ur username Back to the old one and ask if they changed it or someone else did on your account. If that phone number doesn't work Try 1-800 Microsoft

and where might one do that without it sending me to the useless microsoft ai thing
