Telus door to door scam

I had two people come to my door. Both from Telus, one individual named Zayed. Great talker, convinced me I would be getting a great savings if I switched from Freedom Mobile to Telus and would throw in a home security system at no charge! Surprisingly, got my first bill now, says the cell phone bill and home security are two different plans and am getting charged for two services now. These door to door telus sales people are so persistent and complete liars and will say anything to make a sale. Now I'm stuck paying for telus services. Not sure where my savings are. Wonder how many other people have this issue. Absolute crooks.
