Contract upgrade - not keeping promises

I was contacted by someone who said that they were from Cell C, offering to extend my 2 data contracts for another 12 months, with the benefits being that I would receive a brand new wifi device as well as 15c per MB for out-of-bundle data. I was also told that I would receive the device on Friday 7 August. It's now 10 days later and I have yet to receive any kind of device. What I would like to know is the following:<br> Is the person who 'sold' this to me really an employee of Cell C? Am I ever going to get the device that was promised? If the answer to both these questions are No, I would like to cancel this contract on the basis of misrepresentation and breach of contract. And I'm not willing to pay the R300 'cancellation' fee either if this was misrepresentation because I refuse to pay after not being told the truth.
