Platinum Protection Scam, liars, misleading! American Fork, Utah

Had a salesman come to our home and tell us that they are trying to advertise for their company and in return they will install a security system and all its equiptment for free, there is just a $49.99 monthly fee for the call center. He said that there would not be a payment taken out for at least 30 days and that we can cancel at anytime. We had it insalled on 09/30/2011 and then on 10/06/2011 a payment was already taken out of our account. I was not satisfied with their services and felt lied to and misled. I called the customer service line and spoke to a representative telling her that I do not want the service anymore and how do I go about canceling. She said that I can not cancel without paying 80% of the remaining fees (approx $1,560.00) that would be charged for the next 39 months. I told her that the salesman said that we could cancel at anytime. She then told me that the company is not responsible for what the salesman says, they only go off the signed contract. Of course they do, the signed contract we were lied and scammed into signing! What kind of company is not liable for what their employess tell the consumer? This company is a total scam. Do not fall or their lies!
