Real Estate Activities Management Software Resources

I am frustrated and i want to know how can i get out of this fast. They are robbing me of money which i saved to start up my advertising and real estate business. I am about to cancel my CC since they keep charging and are failing to cancel. They keep promising but they donot respond. They are passing days so that they can keep charging. I am not gona pay them what they cannot provide me under the contract package!! No way!!! They will have to bust their a** to take money from me as much as i am busting mine to get this resolved.!!! I need additional help and tips!!!
