Hello.
Please note that this is a community forum and we do not have access to any account data or information.
I'm sorry for the trouble you're having. The only way to recover a hacked account is to follow the steps provided by Microsoft Support;
https://support.microsoft.com/account-billing/how-to-recover-a-hacked-or-compromised-microsoft-account-24ca907d-bcdf-a44b-4656-47f0cd89c245
Unfortunately, if the above method doesn't work and the email address was replaced by the hacker, there's no other effective method to recover your Microsoft account, and Microsoft Support won't be able to help either.
However, you can contact Microsoft Support to request that they suspend your hacked account.
