Prime Minister Harper's Outreach line for Conservative Party.  I called left them a vice message not to call me anymore!

If its Harper calling my Number then he's about to get his [***] kicked soon ><

Get that call daily.  I don't say 'hello' for any number I don't know I make the caller go 'hello' first. If there is no one the other end going 'hello' then I keep the line going until they hang up which is usually about 15 seconds.
