Two of my microsoft accounts were hacked using my backup codes and email, and I cant submit...

I have more information over the hack. The code was a reset password email where they were able to migrate my minecraft account under their email. That's when i lost it. i contacted support there is nothing i can and i cant seem to get anyone on the phone. Hundreds of dollars down the drain

We have recovered the Microsoft account but we cant login to the Xbox live account from the Microsoft account since the hacking. If we try to login to Xbox live from the Minecraft window, it gives us an error code, and if we try to login through the Microsoft email account then it tells us this,

'Why can’t I change my privacy settings?

Note If you’re seeing this page, you were redirected here because you couldn’t change your privacy and online safety settings.

This is likely due to two reasons:

• You’re using a child account that’s a member of an Xbox family group
  
• You’re using an adult account that’s set as a member of an Xbox family group'
  

to answer your question simply, we cannot log in to the minecraft account.

I never used a number on my account i only used email and my email was hacked about 3 months ago they tried hacking my Steam but turns out they hacked my Microsoft as well

My microsoft account was hacked and they changed my email, password and phone number. I still can see my authenticator generating codes. I tryed to recover it but i cant. They say that i cant prove that the account was mine. I dont know how to prove that the account is mine. I have all my documents saved in word and powerpoint on that account and i dont want to lose them + a lost of things in some games.

I can prove that I use this account since 2018 and that it was and it still is connected to my epic games account

I would usually do this but i cant because my password and backup email has been changed so I cannot log into my account
