False Information

In July a consultant contacted me offering me a package which seemed very attractive, I would get more data and would only pay R100 more per month. I specifically asked if I could still buy data if I needed to and add it to my bill, she said I could. In addition, it seems that when the contract was migrated it cancelled my caller line identity and all numbers come through as unknown. I called the call centre now only to be told that I can be migrated back to the Red Select Plus but I would have to pay for it, why should I pay for something that I wasn't given the correct information on in the first place?
