Complaint Review: Credit Report America.com

Since my husband and I are interested in purchasing a home, we thought it would be a good idea to learn our credit ratings in advance. This web site appeared legitimate and offered all three reports, however, When I called the phone number listed I was referred to a onlineline help desk, that can't be found.
Now my dilemma is how to stop being charged for something I don't want and is obviously a scam. How do I proceed?
