Useless business banking

I am so unhappy, not sure why i pay bank charges for a business banker who does not support me with anything. I logged an issue in february and to this day it has not been resolved. My banker is at Standard Bank Mall of the south. I have been sending emails and follow up but nobody seem to care, even with escalation nothhing happend. First i asked them to replace my credit card which got lost, and they did not then i said ok just close the account nothing stil. Not sure who is supposed to keep on paying bank charges for a card i dont have.
