Amazon Business platform verification HELP

Hello there, hope there will be someone who can advise me on what to do with this. I am trying to register and get verified on the Amazon Business platform. My intention is to purchase Amazon products in bulk orders to get discounts on them. I want to get some goods and send them to a different country for local reselling purposes.I have registered LLC in Wyoming state (Amazon Business requires registration as a company) . Got EIN from IRS. Somehow Amazon rejects my verification requests. They are asking document containing EIN (I have that one), and they do ask for address verification (I think this is where I am failing over and over), for address verification, I am providing two documents:

1. Articles of organization (like a birth certificate for my company)
2. Lease agreement with a company that provided the service of LLC formation.

Both these documents contain address where my LLC is registered, but these documents are without state stamps. My register agent (I used northwestregisteredagent service) was told that the documents I have should have helped with that but Amazon always rejects them. They offered to obtain a Certified copy of the Articles of organization document from the state, which would be with a stamp on it, but they ask me to charge an extra 60$ for it. I would love to pay for that if I knew that Amazon will give me the green light with that document.Does anyone have any idea how can I get this sort out?
