Let it ring, they left no message.  Called back, got a voice message saying it was the Conservative Party of Canada, and I was asked to leave my name and phone number and my own message.  Was not offered the chance to add my number to a do-not-call list.

This number is calling me a least 5x a day.When you answer no one answers back so now leave it ring just gets tiring as I need a lot of rest just getting over 6 months of chemo.
