I'm receiving these calls daily as well and am fed up!  As you stated, why can't these low life sludge of the world be tracked and shut down?  Their parents must be proud.

I am soooooooo tired of this caller.  I have never owed the CRA anything.  I don't make enough money in a year to even pay taxes.  Can't someone shut these losers down.  Please!!!!

got a call from this  number  so I called back to see how far I could push this bottom feeder. I was "very descriptive" in my opinion of this low life Pretty sure my number will be placed on a no call list!!  he ended up called me F@$ker before I hung up....
