Not able to access any European marketplaces except Belgium

I’m not able to access my selling accounts for any European markets other than Belgium? I hadn’t used this seller account for a while and I needed to re enter some of my details, but after that all European marketplaces except Belgium were showing that they were terminated. When I tried to resolve my problem with Amazon, I was only able to contact Amazon US, which they can’t do anything about it. Whenever I try to contact any European marketplace, including Belgium, it just shows a sign in thing, but then redirects me to the American Amazon. Any idea how to fix this? I’m also, for some reason, not permitted to access my selling globaly tab? Any help would be appreciated
