Hello,
I’m Sorry you’re having such a hard time recovering your account, I’ll give you some tips for account recovery through the form.
Open this link to reach the Microsoft recovery form https://account.live.com/acsr
Make sure you’re using the same computer/phone/internet that you always used on this account, this will let the system know it’s still you and not an intruder in a different location, while you’re going through the questions make sure you provide as much accurate info as possible, such as old passwords, email subjects, contacts you emailed recently,
If you’d like a more in depth guide here’s an official Microsoft guide .
Your last option would be to contact support and ask for escalation
Open this link https://support.microsoft.com/contactus, select “Can’t sign in”, then choose microsoft365 or outlook account, then “Manage account security” then find “chat with a support agent” or”request a call back” a support agent will then contact you and assist you to their best ability.
Hope this helps,
JC
