Individual Microsoft Store Developer Account Rejected, Support Portal Inaccessible

I registered as an Individual developer to publish my Windows application, AH-Nexus.

After submitting my government-issued ID and selfie, my verification was rejected. Partner Center says my application is closed and no appeals are available.

I emailed the official onboarding support address but have received no acknowledgement.

I also attempted to create a support case through Microsoft Engage Center, but it displays "No Access" and only offers the Support for Business workspace.

Could a Microsoft moderator help escalate this to the developer account verification team?

I need to know whether my existing account can be reviewed or whether I am permitted to register again using a new Microsoft account.

Thank you.
