Ongoing Issue with Employment Verification in Microsoft Partner Program

I’ve developed an AI-powered text analytics application that sits within MS Excel, and I’m currently in the pre-launch phase with initial customers lined up for validation. I’ve incorporated the business, purchased a domain, and completed all necessary banking and tax setup.

However, I’m now stuck in a holding pattern with Microsoft Partner Center. My domain verification keeps getting rejected without any specific feedback. I've hired outside help to ensure its correct and still after multiple attempts, I still receive the following response from Vetting Operations Support:

"This application is insufficient for the requirements of the program. We are proceeding to archive this case."

Unfortunately, no additional details were provided, and I’m unsure how to proceed.

I'll run out of runway if I can't get this app uploaded for users to start using. Has anyone figured out how to get an actual human to look at their application?!?!
