Locked out of Microsoft 365 Business Tenant

I am the sole global admin for my Microsoft 365 Business tenant and I have been completely locked out due to an MFA issue. I cannot access the admin portal, cannot reset MFA, and cannot verify my identity through the automated system.

When I call Microsoft support, the automated system incorrectly states that I am not a global admin and immediately disconnects. All UK support numbers (0800 026 0329, 0344 800 6006, etc.) hang up instantly before reaching an agent. No callbacks have been received despite multiple requests.

I now have an open case with the Data Protection team: Microsoft 365 Data Protection – TrackingID#2609030040002192

This situation has caused:

• Business disruption
• Financial loss
• Inability to manage users or services
• Customer service impact
• Complete loss of administrative control over our tenant

I urgently need escalation to the Data Protection team for identity verification and MFA reset. The normal support channels are not functioning, and I cannot reach a human through any published phone number.

Any assistance or escalation from Microsoft moderators or engineers would be greatly appreciated.

Thank you.
