Welcome to Microsoft Q&A forum.
Sorry for this frustrating situation that you're facing regarding your account being compromised. In case you've tried the Recovery Form but to no avail, it is recommended to contact Microsoft Support to receive direct assistance.
Contact Microsoft Support
- Visit this website: Contact - Microsoft Support
- Type Contact in the search box.
- Now click Get help, and Select Contact Support or Sign in to contact support below.
- Go to the Products and services tab, and choose either Microsoft 365 and Office category.
- On the Category tab, choose Manage account security.
- Go to Confirm.
- You can now choose the option of Chat with a support agent on your web browser.
Important Note*: The Chat support team only works at certain work times, (Monday to Friday: 9am to 6pm. Saturday and Sunday: 10 a.m. to 6 p.m.) so if the last window says you are not available, try to open it again the next day. If you prefer phone support, you can leave a phone number. That way, they can call you and help you. *
Thank you for your patience in reading, we hope this information has been helpful to you.
