Vivint Smart Home, Vivint security Lied to my face about being locked into a contract Nationwide

A few years back I was sold a security system via a door-to-door salesman. Both the salesman at my home and the one I spoke to over the phone told me I could cancel at any time. Three years later due to hardships I called to cancel my service. I was informed at that time that I was locked into a six-year contract. They refused to cancel my service unless I paid another $1600 to "buy out” the remaining time. Vivint is a shady company to do business with. There service was misrepresented from the beginning and there customer service is non existent. Avoid them at all costs.
