Windows Hardware Developer enrollment blocked — all support channels inaccessible

I need help reaching the team responsible for Windows Hardware Developer Program enrollment.

My enrollment is incomplete. Identity verification returned “Verification successful”, but Partner Center subsequently displayed inconsistent verification states and “Pending Partner Action”.

All support routes I have tried are blocked:

• Partner Center: the required Workspace dropdown shows “No results found”.
• Alternative support forms fail on submission or load indefinitely.
• Microsoft 365 support only provides telephone numbers; both calls disconnect before I reach an agent.
• The Windows Developer Support “Create support case (Entra ID)” link opens Engage Center, which says I have no permissions for any workspaces.

I can sign in to the correct tenant successfully. No confirmed support case number has been issued.

How can an applicant whose Hardware Program enrollment is not yet complete create a support case when the documented fallback forms also fail?

Please provide a working enrollment-support route or advise how this can be escalated. I can provide account identifiers and screenshots through a private support channel.
