After updating to elite account no delivery

Both my husband and I recently upgraded to a Standard Bank elite account. Upon doing my application the consultant offered me a credit card and I agreed to get it. Two weeks later I picked up my cheque card and my credit card was not there , when I asked the teller she said there was nothing on the system and took my details to follow up with the consultant Christina who had done the application. A week later I had no response so I went in and another teller gave me the same response , I went in to speak to Christina who told me my credit card had fallen of the system and when she tried to request it again she said my application was being rejected even though initially it was approved , she informed me she was doing a motivation and that she would contact me if there were any problems. A week later which was Tuesday this week I went in again to check and the teller tells me its still not on the system and she would get Christina to contact me. It is now two days later and still no contact has been made. Why does standard bank offer clients products if they are not going to deliver. This displays serious incompetence as numerous employees are of no help.
