Azure AI Foundry model deployment blocked by error 715-123420

I am unable to deploy models in Microsoft Azure AI Foundry because every deployment attempt returns the following error:

715-123420: Our system has detected this request as unusual activity for your account. If you are confident this is in error, please contact support.

My Azure subscription is active and currently has approximately USD 200 in available Azure credit.

I have already tried:

• Different Azure AI Foundry projects
• Different regions, including East Asia, Japan East, and East US 2
• Different supported models
• Recreating the deployment
• Waiting and retrying later

The same 715-123420 error continues to occur.

I also attempted to create an Azure support request, but the support workflow repeatedly redirects me through automated troubleshooting and does not allow me to reach a human support engineer.

Could a Microsoft moderator please help escalate this issue to the appropriate backend team, particularly the Real-Time Fraud Protection (RTFP) / account risk review team?

This appears to be an account or subscription-level restriction rather than a normal model quota or regional capacity issue.

Please let me know what information is required from me privately, such as Subscription ID, Tenant ID, Resource ID, correlation ID, or deployment timestamps.

Thank you.
