Fees for countries outside of the US

Does anyone know how to get ahold of Customer Support via email? No one seems to be able to understand my issues and it’s starting to become frustrating.

I have items listed via Europe, Canada, and Mexico and I’m being charged monthly. However, a year ago, I was notified that my listings were deactivated due to something not being verified. So I decided to cancel my subscription since I was taking a break anyway. But they’re still charging me. I keep bringing this up and they won’t help me. They’ll say they aren’t seeing any fees being charged aside from my prime membership
