I wanteed to bring up a point . It is December 9, 2015 and I have noticed a number of telephone calls from security companies. Prism is one of a long line of these scumbags. Before Prism's call I got one from Grand Security and there was one before that, but forgot the name. They seem to come in batches. The telephone numbers are all different but I'm wondering if this is a ploy used by one company with a number of aliais trying to trick you. All I can say is if you pick up, never, never, never give them any information and never, never, never buy their product or services. This is the only way, we the public can stop this madness and run them out of business. Good luck to you all. Caveat Emptor!
