The caller ID read, "NOT IN USE," so apparently these clowns are so inept they can't even spoof the name. Do I want an alarm system from them? Since it would probably call the gas company to report a burglary, I think not.
Received call a few minutes ago; this number has called several times this week. Let 'em call: they go right into voice mail if I don't recognize the number on Caller ID (the best tool for this kind of nonsense), and they scarcely ever leave a message.
