Dishonesty and misrepresentation to make a sale.

I was contacted by an agent from the Vodacom Centre to discuss my high data expenditure. The agent offered me this amazing data deal for R289.00 per month. I was most definitely interested in getting this deal but made it very clear that I did mot want an additional simcard. I requested for this additional data to be added to my existing line ***. I was told that I have to take the additional simcard and that I can just transfer data from one line to the other. I explicitly asked after having mentioned my number if I would be able to transfer to that number and was assured by the agent that this was indeed possible. He even went as far as explaining to me the *135# process. I have been trying to transfer data when my data ran out only to discover that my line does not qualify for data transfer. The agent was dishonest and misrepresented what he was offering me. I want this line cancelled because I did not get what I agreed to.
