Trouble with account - pricing adjustment & added service

I've been trying to switch to Telus home internet and tv since October24. They finally were able to come to my house Jan 2nd (after 4 previous home visits since Oct24 failing to perform service) and get the service set up. That evening I received an updated contract with different pricing than what was agreed to on the original Oct24 contract, and an added home security service which no one had discussed with me. I've spend numerous hours on the phone with Telus support to try and get this resolved with no results. Is this Telus trying to scam people into increased pricing contracts and services? I did finally get a manager who escalated and provided a case #, but after she called me back twice she cancelled the case. Does anyone have any suggestions on how they have contacted support and been successful with getting help.
