Customer Service Broken Promises - Not being honoured what was offered

And here I was was thinking that I was the only one with this problem, I was suppose to get 1 phonefor free, 2 lines for 70$ +tax with pre-authorized paymentsas a business account and 80$+tax without pre-autorized payments. The rep's name was Cheikh [mod edit - privacy] that sent me the overview of the offer that I was auppose to get and asked me to confirm that I agree to the offer, so I did and asked him about all the extra payments that involved with this transaction that were suppose to be wavered, had 6 month on the old contract left with a cheap phone that at the end of the term would be 100$ if I kept it, so after I get a bill of 586$ additional payment for the bring back device (100$) and some other fees that I do not get how everything ended up being that much. Asked abother person to investigate the whole thing and out of 4-5 conversations that I had with Cheikh [mod edit - privacy] there was only 1 recorded phone call that didn't have any information about the wavered costs and fees (how convinient for telus).  Been calling telus and being bounced from one person to another from in different deparments, nothing is being done and the amount of the bill comes to 120$ for 2 lines, a difference of 50$, I had 1 line with Telus I was paying 50$ and 23$ for the second line with fizz, of the offer above wasnt 70$ for 2 lines I wouldn't have changed anything at all, should have kept paying 3$ more per month and not have this lind of headache where you stay on the line for over 2 hours bouncing from one department to another. As I see telus is becoming a big scamming company that wishes soley their name and loose all the customers. I've been with telus for about 20 years and never had such problems before. Even fido and rogers have better plans and slightly better service, but as a fool I was loyal customer with telus and went for their scam.
