Harass them right back!!!!  I call the "Home Security Promotions" scammers right back on 201-857-9080 - over and over and over again.  Sometimes I don't say anything, sometimes I crinkle plastic near the mike, sometimes I randomly press numbers to send them irritating tones, sometimes I use a fake unintelligible agent to keep them on the line.  With unlimited minutes on my phone, I redial them when I'm driving, when I'm playing computer games or watching TV - sometimes up to 200 times a day.  It is quite satisfying to know that I am tying up one of their lines and their staff preventing them from scamming others.  The best reward is to hear the growing frustration of the scammers as I continue to call and harass them. Over and Over and Over again.
