US Market is not showing in my UK Seller Central

Hi,
I’m selling in UK from last 2 years now I want to expand my business in US for which I’m done with all legal requirements like LLC etc. But when I jumped into my UK seller central to check & register for US market it says “One of your seller account is terminated please use new credentials for registration”.

Then I opened the case with UK seller support team they said all your UK & EU marketplaces are perfectly fine you’ve to contact US marketplace team to check for issue.

When I jump into global selling and then Americas Market then register for an account it still shows the same & i can’t see any option to contact US marketplace team.

Can somebody please guide me how I can sort out this issue or how can i contact US marketplace team. @The_Little_Shop @Retro_Emporium
