Just received a call from this number 1-647-495-9156 at 9:25 at night (pretty late) March 13 2013, the man stated he was from a security systems (didn't catch the name), then he asked me if I had a security system in my house, I replied with "I do not give out that information". He then asked me why, I told him "I don't give out that information over the telephone", then he said bye and hung up right away.
just got a call from this number, waited to hear me respond and then hung up. tried to call back, only to get a busy signal, as he was probably calling the next victim. thanx for wasting my time
