They hacked my account, the code to change the password is sent to a different email address

My Microsoft account was hacked, the password was changed, and when I try to send the password change code, the code is sent to an email address unknown to me: wn*****@igloo.st. The account was hacked approximately within two weeks because I didn't check if it worked at the time. Yesterday I checked and it wasn't working anymore. Minecraft was working for me, but today I was logged out of it. What can I do if I don't remember the old passwords, only one old one, and Microsoft requires two?
