Unhelpful business banker

I recently registered an Inc and wanted to keep my banking with Standard Bank. I use them for all of my banking products (personal and business). It was inconveniencing enough that I couldn't update the details of my existing bizlaunch account to the name of my now registered Inc-I had to open a whole new bizlaunch account (still for my private practice, as the sole director). Now for the past 2-3weeks I've been getting no joy from my business banker with linking my new bizlaunch acc to my app and online banking. Prince Maoto is not only slow to respond, he doesn't acknowledge receipt when you send info he's asked for, lastly his tone is impolite and short. I am over his service, or lack thereof. I am feeling concerned as I have requested to close my old bizlaunch on the 4th March and am suppose to have full access to my new account without any glitches.
