Nedbank not keeping promises

Now really the worst bank ever. On the 29 of august they phoned me again and then in the conversation the lady told me that I have a credit card loaded to my name and that another guy will phone me to get my details. Then I asked her several times if I am pre qualified or is it definitely mine. Then she rep**** several times that it is mine for sure. Then when the guy phoned me he says I dont have it. But luckily the call was on my car Bluetooth and my passengers herd it all and even recorded it for me. So now if it is not resolved in a few days I will be contacting the CPA and NCC and then the banking ombudsmen. I also have plenty people willing to close their accounts if I do.
