Hi, good day!
Even if you contact Microsoft Support, they cannot recover your account on your behalf. They can only direct you to the official account recovery form, as it is the only method available for regaining access.
Since this is a public community forum, no one here has access to your personal Microsoft account or can assist with the account recovery process directly.
I know how stressful this can be. If the hackers have already altered your email address or recovery information, regaining access becomes significantly more challenging.
Your best option is to follow the interactive Sign-in Helper tool found in the official guide linked below. It will guide you through the available recovery steps and outline how to reach Microsoft's support team if options remain. Please keep in mind that if these official channels fail, the account might unfortunately be permanently lost.
