How the heck can I get rid of Mexico marketplace? It doesn’t allow individual seller plan and I don’t want to pay professional seller subscription

I just want to sell in Canada and I have not set to individual. Anyway I got hit with $500 in seller fees for months and months of professional plan for Mexico marketplace, I didn’t even know I signed up for Mexico (yep read the small print) anyway how can I delete this marketplace so I can stop paying the professional subscription??
