Address tied to DUNS number not verifiable

I've been trying to sign up for the Windows developer program but the address associated to my DUNS number cannot be verified by Microsoft. I also can't enter a different address manually because the button doesn't do anything, please see attached screenshot. This won't let me move past the Company Information page. The address is correct, the company is registered there.

I also can't file a support ticket because I don't have a workspace to attache the ticket to. This whole process seems to be broken. How do I proceed?
