Trying to get hold of my Prestige Banker

I am so disappointed with Standard bank Prestige banking. I have been trying for 2 weeks now to get hold of my Prestige Banker. The Call centre has helped me with my query, But i still need to speak to my Banker. I have asked a number of times for my account to be moved to the correct branch, Still nothing has happened, I have asked a number of times for a Banker to call me... No response. What do i need to do get assistance? I am unable to walk in to a branch, i mean why do you have these services. Do i need to join another bank. I need some for standard bank Prestige banking in the Milnerton Branch to contact me Urgently.
