Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Account recovery is an online automated process, even if you are able to contact Microsoft Support, they cannot recover your account, they can only refer you to the account recovery form.
This is a widely reported scam on Discord, I wish I had better news for you, but when a Microsoft account is hacked, if the hackers change the associated Email... etc. or if 2FA is enabled on the account, then that account is usually no longer recoverable, this forum is just a user to user account and no-one here has any account access, try using the process they provide on this link to recover a hacked account, if this process is not successful, sadly, that account cannot be recovered.
