How to Get Microsoft Teams Phone Service Refund - Support System Completely Broken

I need help getting a refund from Microsoft for the Teams Phone service that has not been provided for 6 weeks.

What Happened:

• Paid for Teams Phone - Domestic Calling 6 weeks ago
• Cannot activate due to Microsoft's broken domain verification process
• Multiple support agents across different teams - all incompetent
• Microsoft admits their phone services are "not operational" with no ETA

Current Situation:

• Agent took ownership of refund request days ago
• Complete radio silence since claiming it was "escalated"
• Still being charged for a service I cannot use due to Microsoft's own system failures

What I Need:

• How to actually get a refund processed from Microsoft?
• Escalation contacts for refund issues?
• Anyone successfully gotten refunds for unusable Microsoft services?

Business Impact: As a small business CEO, I've wasted 6 weeks and lost revenue dealing with Microsoft's dysfunction. I no longer want their service - I just want my money back.

Has anyone dealt with similar Microsoft refund issues? How did you get it resolved?

Any guidance appreciated - their support system is completely broken.
