Private Banking Horrible Experience!

I app**** for a credit card limit limit through my private banker way back on the 14th of August. Since then its been an utter nightmare trying to get hold of the Private Banking team, no answer to emails, no phone calls picked up - its absolutely terrible. I did it early in the month hoping everything would be sorted for me to do what I needed to do then. Now the delay has had a very severe ripple effect and there is no one to get hold of. When you call the limits division of Standard Bank all you get is that only the private banker can do the change which is extremely upsetting when they dont even answer . Why then bother call it private banking when the most desperate times are when they are unavailable??? its been 3 weeks trying to do this process. I am really sorry to say but Standard bank have been extremely poor here! These are the moments when a bank's service record gets called into question and they have failed miserably. I stood by them because I am a long time client but to be honest, the private banking offering used to be good but over the last few years it has severely deteriorated. My advice to anyone, better to go to fully designated private banks
