Same old scam call from the same old people spoofing different numbers. They've called from 305-602-0793, 240-318-1595 and now this 305-747-3904 number. It's a fake "telemarketer" claiming to sell alarm systems (from what I gather from other post), but I'm pretty confident it's facetious people trying to get information from you. The key being if you have an alarm system protecting your home. Which that information should never be given out.
