Verify your account information when you enroll in the Microsoft Cloud Partner Program

Unfortunately I too am stuck in this loop where I can't get verified, I've worked in the partner channel for more than 20 years and have decided to set up my own company in the UK. My issue appears to be around the employment verification, i've uploaded 3 separate pieces of paperwork, all of which have been rejected with no clear reason specified. After the first two I thought that it was possibly because the email address didn't match - I purchased the domain using a private email address as you can't buy a domain with an email address on the domain you don't yet own! So I updated my email address and purchased another year on the domain, that invoice was then rejected with no explanation. Then I've been stopped from making further submissions and was told that my partner account would be closed in 30 days! I tried opening a support ticket and it's taken them 6 days to come back to me to tell me that they're closing the ticket as my details didn't meet verification but again they provided no details.
I'm a limited company, I have a VAT registration, i've purchased the domain and it's in my company name, address and email. Everything appears to match and yet i'm constantly being rejected. I've left my job of 13 years to do this and now feel like i've made the worst mistake of my life.
