Hi Maksym

I understand how difficult this situation must be, especially when being locked out of your Microsoft 365 tenant is disrupting the work your nonprofit organization depends on 

Please note that Microsoft Q&A is a public user-to-user support forum, and we are not Microsoft Support. As forum moderators, we do not have access to Microsoft's internal systems or the ability to escalate cases directly to Microsoft's internal support teams. Our role is limited to providing technical guidance and sharing best-practice recommendations based on reported issues, requests, and scenarios. 

Based on your description, since the Global Administrator account is locked out due to the lost MFA device, only Microsoft Support can assist with recovering access to your tenant. 

If you are unable to reach the appropriate support team by phone, you can consider directly submitting a support request as a helpful workaround:     

-Create a temporary Microsoft 365 tenant using a trial license: Go to Microsoft 365 Business Plans and Pricing and click Try for free to set up a temporary Microsoft 365 tenant with a trial license.    

-Use this new account to sign in to the Microsoft 365 Admin Center and submit a support request on behalf of the affected tenant.

Note: This method doesn't require you to use your new account for your business. Instead, it allows you to create a temporary global administrator account so you can submit a support request, as your original global administrator account is locked out due to issues with multi-factor authentication. The trial account is free for one month. Be sure to delete it after submitting your support request to avoid any automatic renewals or charges from Microsoft.

Thank you for your patience and understanding.
