Someone from Platinum Protection came to my home to tell me that they were installing free systems for some homes in order to promote their company. They would do it for free if we put a "Monitronics" sign in our front yard. First of all, the system was a joke, and their "support" was even worse. But it was better than nothing.
But then I had to move for work. I tried calling the company repeatedly when I'd get their invoices, but no one would ever return my calls. Eventually the invoices stopped. That was more than two years ago. Then I was notified I was being sued by the company right before the statue of limitations ran out. I was given 12 days to pay or face a lawsuit. They claim you can't cancel their policy; all you can do is resell the policy. The person who sold it to me never notified me of this ridiculous policy - or told it was for a staggering five years.
Do yourself a favor. Stay far, far away from this company. There's a reason it's rated an F by the Better Business Bureau. http://www.bbb.org/utah/business-reviews/burglar-alarm-systems-dealers-monitoring-and-service/platinum-protection-in-american-fork-ut-22169304
