price plan changed

My price plan for 3 lines changed in between the contract term. they removed discounts they offered at renewal & sold me plan & device for 2 year contract term.  but now changed price & breached  contract . will go to court as i have all emails & conversation they offered me at renewal time, big scammers company fooling people to switch from other service provider to telus with wrong pricing & promotions . please don't use telus service & recommend any friend to use telus.
