Got one too.  Lots of posts on the web about Eco Health Solutions.  Giving away $ 300 gift because we filled out a survey (which we did not).  What I gleaned from the posts - the gift is useless and they are selling an air purifier worth $ 100 for around $ 3,000.  Tell them to take a hike.

Called saying I or my wife filled out a questionnaire. We did not! They are using this script to get around the DNC list, but they are lying. They are using a number of different tel numbers to make their calls. Just hand up!! I am reporting them to the DNC registry as they are clearly contravening the laws of Canada.
