Daily Calls, never leaves a message or anything

Called saying it was alarm monitoring and we already had system  as he asks right? Hung up but sure makes ya wonder   Isn't this great. Caller Id and if you say no alarm they call later and you aren't home then it's open door to them.  They have your address they know no alarm maybe they can park out front and call from a blocked cell phone to see if anyone answers.  We should just put our valuables on the curb and let them have it I guess.  Who can we report this crap to?

I received a call from this number at 6:34pm today.  No answer when I picked up, then an automated "goodbye".  I called back, someone answered, said his name was "Roy" and wanted to know how I got his number. I told him that he called me, then he addressed me by name. I did not acknowdge that, and asked again who he was.  He said, well, actually it's about your security system.  I hung up.  Ver disturbing.I want to know why I am getting these calls when I am clearly on the do not call registry!

Don,t let him or whatever they are come around to your place. Id report it soon. I calculated 5 calls in february here. I will phone them back at some point.....I am Mad at this...

This thick indian accent just called me now from the same number ( (905) 695-9048 ) to sell me security system, which i told the i have one, and am not interested, that's when he said i will come to check it, of course not, i know they are fake, sound like it.. Very thick indian accent

annoying call.keep calling.
