Customer Service Broken Promises - Not being honoured what was offered

As I see I got the same broken promisses from Telus, business rep made me a good offer of 70$ for 2 business lines, I got a bill for 120$ for these 2 business lines. Another business rep is telling me that it's normal due to me having before a consumer telus line that was transfered to business and thus I have to pay higher price and do not deserve the promissed business plan. I've been on the line for hours being bounced around from one deparment to another and some reps even dropped the line, I would understand if it was once, but 3 times makes you feel unwelcomed.
