APEX Alarms/Vivint  False promises and broken agreements Internet

I was contacted by phone the first week of December 2010 by a representative saying I had been chosen to receive a free alarm system and one free months of service. I was required to pay for the second month up front but was told I could cancel at any time. They set an installation date of December 22, 2010. The day they came the grandchildren I have custody of were having Christmas at my home with their other grandparents so they did not spend much time and again stated I was obligated to pay for the second month  but the first month was free and the equipment was free as a marketing promotion all I had to do was allow them to place their sign in my front yard. The first of February I received a bill for January 22, 2011 to February 22, 2011.I called explaining I paid for this upfront and that December to january was suppose to be free i was told it would be corrected at the same time they were sending someone out to install a thermostat that could be controlled from anywhere. This scenario continued for several months until I finally told them that I was not paying anymore until they corrected the account and stopped reporting me as delinquint. Now I have collection agencies calling and bad credit reports from a company that broke the contract by one trying to charge me for equipment that was supposedly free and two trying to charge me for a month that was on my paperwork as free. I requested they come get their equipment and correct the credit reports with no satisfaction. Recently I have received at least ten calls a week from collection agencies I am filing a report with the credit bureau and the attorneygeneral for these frauds!
