The same here, just got a call now and none answered. When I called back got an electronic message.
I remember though getting a live call previously from Ontario Eco energy where the lady explained the 3000.00 dollars rebate but I did hang up on her after saying everything is updated in our home .
This number should be blocked from your provider. This number is based outside of Canada even though they have a Canadian number .(My account is highly secured ) I have been told from my provider that the parties try to still your information through the phone such as phone records, credit card info, name etc.... The CRTC will also be notified regarding this information !!! PLEASE DO YOURSELF A FAVOR AND BLOCK THIS NUMBER !!!!
