I kept getting the call from this number , I said you are calling a wrong person ,still they call me

I got a call asking for the home owner. When I asked his name he said "Randy White" and he works for the company named "ecoEnergy". His telephone ID came up as (289) 268-5268 but he said his real number is (416) 800-0365. When I googled (416) 800-0365 it turns out to be the Ontario Gov't ecoEnergy Rebate program which has lapsed. I told him the Ontario Government does not call home owners and arrange visits to their home. I asked the so called "Randy White" if his phone number is (416) 800-0365 why he calls me multiple times from (289) 268-5268. He says to save costs he uses the internet phone and it keeps hanging up on him. I strongly believe this is a SCAM!!!
