Worst Banking experience ever! And it's only day one

I have initiated contact with Nedbank and was told that I would be contacted by a banker to assist me with moving my bank over. Nash Chadd from the Gardens branch contacted me via WhatsApp to get me signed up and once he did contact me, he mentioned my banker would be in contact with me to sort out logistics. I then called into the call centre to get my banker's information as Nash Chadd has gone radio silent. I was told that I'm not getting a banker and would need to call customer services for any assistance. I just want to know what is actually going on? Who do I contact? Do I have a banker? Apparently my cards aren't loaded? Just any feedback???
