Over a month to open an account as an already existing customer

I have my business banking with Absa. I app**** for a credit card which was approved the same day, however, it has been over a month since then and I still do not have the account or card. I have spoken to the banker endlessly, I have lodged a number of complaints to which I get an Email saying it is being reported and the complaint closed with absolutely no movement or action taken. The call center just rings, my banker just makes excuses about how he is new and doesn't really know the process. It is embarrassingly *********** and is hindering my ability to properly run my business.
