I am sick of this number calling me at odd hours and no one there. I live alone and get scared.!!!!!!!

The person called then when i answered the person didn't say nothing then when i called back, they say the number is disconnected

stop

This number called I was asleep at time time taking a nap my young sister answered the phone. The guy starts asking her all these personal questions like where are her parents? How old is she? Stuff like that, I take the phone from her cause now I've woken up and ask who he is. The guy won't answer so I hang up. Call the number back from my cell to see how they answer like if its a telemarketer an the recording tells me the number has been disconnected. I'm freaked out!The guy had an accent.

Yes.  They had hung up after second ring.  When I tried calling back the operator voice mail said the number had been disconnected.

Yes it is someone claiming to be an air duct cleaning service. It is a scam and they are always calling from different numbers. Please call and report it to the Canadian Do Not Call List. I finally called about a year ago to report it and was told its under investigation and to continue reporting the phone numbers they call from so they can be tract.
