Thank you for posting this in Microsoft Q&A.
As I understand your device in Azure AD is disabled and you are unable to login to the device.
To enable the device you will have to contact your Global administrator of the tenant. You also mentioned that your admin is not responding to you.
Usually there might be multiple admin for your tenant. You can try to send an email to any other Global admins of your tenant to get this device enabled.
You can run below command to check who all has Global admin role assigned,
- Open Windows PowerShell as administrator.
- Run command "Connect-MsolService"
- Enter your credentials
- Now once authenticated you can run the command "Get-MsolRoleMember -RoleObjectId $(Get-MsolRole -RoleName "Company Administrator").ObjectId"
- You will get multiple users as result with there Global admin role assigned.
- You can send email or contact them in any other way to get your device enabled.
Let me know if you have any other questions.
