How do I speak to an actual person regarding Microsoft Partner verification?

Question

I've been a partner for several years, and due to changing the address listed for support, a verification process was triggered, which we failed on the employee verification section, and cannot submit any more attempts. I've since opened a ticket where I explained the problem, whereby they keep asking for the same document over and over, which we cannot provide, a receipt for domain renewal. After waiting 5 days, no reply was received, so I contacted them again on the same ticket, and they asked for a receipt for domain renewal... Since then, each sporadic reply is just a canned reponse with maybe one human reply.

At the core of the issue, we've always just renewed our domain with our domain wholesaler alongside our client domains, so we just have an account credit/pool, which means there is no conventional invoice for any single domain that lists the details they want, and we obviously cannot invoice ourselves.

Realising that the support 'people' doing the verification were just going to keep asking for it, I transferred the domain to Godaddy, but its an Australian domain name, and was only renewed last week with our wholesaler, so we cannot trigger a domain renewal with Godaddy for several weeks/months, and Australian domain's cannot be renewed/prepaid for any more than 2 years.

I have since provided the transfer invoice to the support person, and got an AI reponse back on the ticket saying to lodge it with the verfication tool that I am locked out of. The actual ticket thread never seems to factor anything in other than the most recent reply from me.

How do I actually speak to a person, either via email or phone? It's exceedingly frustrating to be spending so much time trying to work around what appears to be a completly broken system.
