App store doesn’t work

I wrote a whole lot and lost it, so I’ll keep it simple. I had downloaded an app Mcaffey Security because of the free trial they were promoting. The app is pretty useless, not detailed enough, and other problems, but I could go on. I cancelled the trial and removed the app. Well less than a week later I was charged for a WHOLE YEAR of their worthless service. I don’t want one day of it and I would never purchase a year of it. After failing to contact them, I was forced to go to the bank and stop payment on it. Now I have another problem. Every time I try to go to app store or update and app, i get “your account has been disabled in the app store and on itunes”. I can’t even update my banking software. I don’t want the Mcaffey crap at all. What gives?
