Amazon Small Business Badge - Help please

Hello, I’m trying to apply for the small business seller badge. After contacting Amazon to request this I was told to request a Dun and Brad street Number (DUNS).

Which I have now done and I have received my DUNS number from Dun and Bradstreet.

I have sent my DUNS number to Amazon, But just keep getting the following reply:
