Unable to get my hacked account back (minecraft)

Hello everyone, I really need help to get my Minecraft account that was hacked a year ago back. The hacker compromised my Microsoft account and changed all the security information. I’ve contacted Microsoft 5-6 times to do a account recover and found the support quite poor. I’ve been told twice now by the team that my account was indeed compromised but there is nothing they can do due to the information being changed. Is there anyway I can still get my Mincraft account back or transferred to another Microsoft as this is just ridiculous a major company can’t control there own users accounts.

:)
