(for Canadiens) How can I get a better deal on my monthly phone bill?

Right now I have Rogers and 40$ a month is too much for what I get. I don’t even have call display or voice mail. I can’t leave because of my contract and the deals out right now suck. I’ve heard of some people who have had some luck getting great deals over the phone. What should I do ? Is there a way to switch carriers without outrageous fees or is there a way I can sweet talk my way to a great deal? (also would I have to pay fees to switch to fido since they’re the same company?) Thanks
