Help me recover my account.

Hi,

My other Microsoft account was recently compromised but it was compromised before as well. When it was compromised before, the hacker added a recovery email for verification and to remove that I added my another email and the request was sent and it was supposed to change in October and I was not able to change the password or use other features of Microsoft because at some point it keep redirecting me to the page that I have sent a request but during that time period, my account was compromised again and I keep receiving emails of unusual sign-in activity by the hacker and I wanted to change the password but I couldn't because of that request so I was being patient. Now I received an email that someone accessed my Microsoft account and now I have to verify my identity to log in and to log in it ask me to type the email that the hacker set up because it's not changed and since I don't know what that is it takes me to the account recovery page where I put all the information that I know, I write in my postal code, my old and current passwords, date of birth etc. I have never used skype, Hotmail or outlook and Xbox so I just uncheck those boxes and then it asks me if I have ever bought any product but since I didn't so I uncheck that as well but then I just receive the email that the information I provided is nonsufficient even thou I provided all the information that is correct. Unfortunately Sign-in helper didn't work.

Kindly help me resolve the issue.

Looking forward to your positive response.

Yours sincerely.
