Microsoft account compromised

Hello, My Microsoft account linked to my Gmail (which I still have full access to) was hacked. The attacker changed my password and added their own recovery email. I received a message saying the password was changed, and now I am locked out. I have already submitted multiple recovery forms via https://account.live.com/acsr, but each time Microsoft denies the request, even though I can prove that I own the Gmail address and used this account on my own devices. The hacker added the email: du*****@dcpdrocas.com and changed the password . I still have access to my Gmail address and can verify identity through any method Microsoft requires. I’m requesting help to escalate this to the proper recovery team or support escalation. Please help me recover this account. I need access to it urgently. Thank you in advance
