Service & Communication to resolution

I have logged numerous of calls and spoke to more than 5 agents in the last month and a half from Nedbank. Nobody from Nedbank management will contact me back or even respond to any of my requests to have the necessary discussions at all. I have been a loyal customer for more than 17 years and this the service I get. My personal banker is not even getting involved, so what is the purpose of a personal banker if they cannot even jump in to assist customers. My wife is also a Nedbank client and I recommended that she joins the Nedbank family, but she also struggled with her personal banker, just to get a bank card. She eventually had to go to a Nedbank branch to get this resolved and when they asked who the banker was, the staff in the branch had a strange comment about the banker. This just confirmed the poor service from Nedbank.
