Misrepresentation

I have been having a bad experience with the company they are handing my standard bank credit card matter. They promised me a 40% discount on my debt and now I made payment the 40% discount is no longer on the table. The agent that promised me is Khanyisile Alicia Molefe. I have asked her to call me back and as always she makes promises she never keeps and doesn't call back. I have asked for written estimate after the 40% discount she refuse to send but will tell me over the phone. I asked for the recordings of our telephone conversation, and I have been promised I will receive them and still no feedback or response from the company.
