Trying to expand to the UK

I have spent days trying to expand from just selling in the Americas to selling in Europe. I was eventually told that my current account wasn't able to expand because it was too old. I now created a brand new Amazon account just to get access to the UK and link it back to my initial account. I have set this new account up, but again I only have access to the Americas marketplace. When I go to the "sell globally" page on my Amazon Seller Account, and select Europe, it says registration incomplete. When I click the "continue" button it says:

----"Page not found The requested URL does not exist. Please check your URL and try again."

When I specifically sign into amazon.co.uk and try and access Europe from there it gives me this message:

----"While we verify your credit or debit card, you can start exploring the 'Seller Central' of North America"

I signed up over a week ago, and it's still not ready. I've spent countless hours talking to Amazon support on my other account, but I don't even have access to support on this account so I don't know where else to go. If someone knows how to fix this please let me know!

Thank you
