Telus Intermet serice agreement issue

HI, 

please advice and point me in right direction of what to do in this case.

i found someone offering a good deal on marketplace for telus internet.

so i talked to guy and got the internet connection (so far good)

then i recieved service agreement but price was not what was promised so i talked to him and he assured withing couple days i will get another agreement with all the cost as we discussed.

now i have been talking to him many times since and havent recieved any changes in agreement. 

the cost on current agreement is way too high. and i dont see the person helping me out in getting the promised rates. what should be my next steps ?

please help and advice.

thanks
