Called at 9AM on a holiday Monday waking up the house. All we got was a machine noise and then a hang up. Called the # back, busy, then on 2nd try got to the Rogers "this customer has not activated voice mail" message.  Pretty clearly an autodialer.
Yes...we are on the National Do Not Call List.... what a joke that is

I'm also on the national do not call list! But I keep getting these phone calls too and I'm starting to wonder if that's just something they tell you. I also got a call from this number saying it was duct cleaning, not sure if it's true or not.

A-1 Duct Cleaning, so caller said.  Could not give me phone # or address of company.  Wanted to get Supervisor--I hung up!

Called and hung up

Got a call as well.  I suspect people who make this kind of calls are probably foreign students or visitors that can NOT work in Canada without authorization.  This is because no one can possibly make a living this way.  A few years ago, I managed to get the name/address of a recruiter, and then went to CRA in order to stop the recruiter who seemed to harass me for a living.
