I'm being charged for 7 domains, but I only have 4 domains showing. How do I get this fixed?

I went online to delete a domain, but when I went to "Domains," it didn't show, so I thought perhaps I already did it and forgot. It showed the proper 4 domains there. When I clicked on my account, it showed that I am paying for 7 domains. I need this to get fixed, please.
