Just received a call from that number asking me if my alarm system was more then 3 years old.

Calling asking if alarm system was more then 3 years old

Received a call from this number about half an hour ago.  No message left, therefore not an important call.  If it is the home alarm system scammers as mentioned by Sue above, this now makes the 11th number these scammers have used to annoy me.

BTW, Sue...don't refer to these thieving criminals as a Non-Profit Organization.  They're looking for one thing, and one thing only...to relieve you of your money and/or your personal identity, and they'll use whatever tactics people are stupid enough to fall for.  They're as much of a NPO as I am a real doctor (in my case, it's just an old high school nickname).
