Help! I cant cancel my account

I can't cancel my account, but keep getting charged. Anytime I enter my card under my personal account it get saved under my business account. I obviously screwed up in the setup process, but who do I call to get into my seller account so my personal account isn't being charged for seller charges from mexico/Canada/uk/fr/esp/br. This is a lot of money when my card has been inactive from my bank for a long time. I may not have communicated this well, but to try and cancel my seller account after a fraud charge on my card, they are charging me for countries I never signed up for. Still, I can't cancel. I can't add my card to my personal account either.
