Sales person by the name of Josh. Came to my address . Josh said he was athurorized by the HOA President to sell home  security system. He did not have a letter but he did say her name. With that i listen to his sale pitch. It was  as  usuall it was a full court press. I was in a hurry. I was told to sign because I was told it was a trail period. I was told I had thirty day to cancel. The system malfunction in less than a week. I decide to cancel the service. I tired calling Josh. Voice mail was unavailable. Called customer service. Was told they would get in touch with Joshu to get what kind of cancellation I was sold. No one called me back. I called and  sent several emails to cancel and pick up there equipment . No respponse from Vivint. i fell like I was lied to several ways. I felt like Vivint lied to me to get in a five year contract. I am pissed on low they went to trap me . I am ready to go to court. Please help me.
