Recently created an Amazon seller account for the UK marketplace, but my account was mistakenly activated for the North American marketplace (Mexico), while the UK & Europe Marketplace also Active.

I have two concerns:

1.How can I deactivate the North American marketplace and ensure my account is focused only on the UK & Europe marketplace?

2. Does the subscription fee apply to both the North American and UK Professional Seller Plans, or will I need to pay separately for the UK marketplace ?

I would appreciate your guidance on resolving this issue so I can proceed with selling exclusively in the UK & Europe marketplace.
