$30/month each mobility line offer to switch to Telus provider became bogus

Same thing happened to me...got a call from a Telus rep that lied about lower prices for 3 lines.  Wgen I checked the bill I was horrified...he said it would be around $100 a month and it was $370 a month! And what's worse is none of the reps from customer service could help me resolve this issue. So im basically screwed. I cant get out of the contract and Im told too bad I'm stuck with it! SCREW TELUS...NEVER AGAIN!!!
