Hello, thank you for reaching out to Microsoft Q&A.
Keep trying the account recovery form. Because Microsoft Support cannot grant you access to your account, you will be returned to the Account Recovery pages linked above.
Remember to use a familiar device from which you've frequently accessed your Microsoft account, as well as a familiar location. Microsoft will review your responses and respond within 24 hours. If you are verified, instructions on how to log back into your account will be sent to you, and if you are not verified, you will need to submit the Account Recovery form again. You can do this up to 2 times every 24 hours.
If your Microsoft account recovery request was not granted or was unsuccessful, please click the attached link for more information: Account recovery unsuccessful
Alternatively, you can submit the Account Reinstatement form to the Microsoft Account Digital Safety Team to review the reasons why your account was disabled and help reinstate it if possible.
