Do not know who called...

Called at 6:40pm - nobody on other end.  Hung up.

Air Duct Cleaning company, they say they are from my area, but didn't say what the area was, speaker was female with broken english, not a good telemarketer at all, after I heard her introduction, I said I wasn't interested in Air Duct Cleaning, and they immediately hung up on me.

Got the call, my wife answered, no response.  I usually don't answer when I don't know the number.

I had a call from (613) 987-6589.  When I answered there was no response.  I hung up, called the number back, and was told that this number is no longer in service.

Thanks for the comment Hugh. Will report these scammers to DNCL
