Canada and Mexico Marketplaces

I received an email that I was charged to settle my account balance in Canada and Mexico. I don’t sell anything in these countries and when I checked my transactions I’ve been charged a service fee for these countries. I didn’t know it, but I had several listings that had no inventory listed in those marketplaces and one active FBA. I have removed those marketplaces from the listings, but how do I make sure that I am not enrolled in those countries still and being charged a monthly service fee?
