Standard Bank not helpful in ugrading account

Dear Peter<br> <br> I am disgruntled by Standard Bank Private banking. I called them two times asking to upgrade my account from prestige banking to private banking but they are failing to secure an appointment for me. I was told that someone was gona call me but its not happening.<br> <br> My question is that, Is there a cap on the number of people who should be doing private banking or people responsible for private banking do not want to do what they are paid to do?
