Keeps calling with no one on other end, annoying.

I just got this call saying they were a security system installation company. ?I told them I already had security in my home, and he asked IF IT WAS MONITORED.  I said "yes, it's monitored" and he hung up.  I don't like the fact that he asked about monitoring.  If it wasn't monitored, would I be the next "break in" or "home invasion".  I will be passing this number on to the police.

called me around 830pm on a friday, I answered, then they hang up?I called this number back, it replies with a message saying the person is unavailable and you can leave a message

Called at 8pm on Friday night - told my husband it was a security system company. ?My husband told him we already have an alarm system and then he hung up.

I just got a call from that number and work they sounded like s***. Could not understand anything. Like when are they going to get the hint if we really wanted what they were selling, We would call THEM!

I think this young man is a very lonely person and can become desperate.  The authorities or his parents should be alerted.  I asked him why he keeps calling my number and he just replied: "Good day!" and hung up.  What a strange creature, I think he has too much money, watches TCM all day, eats take out, probably lives on a golden trust fund.  A really pitiable creature!
