Standardbank poor business banking service

I called my business banker a few days before a customer would pay money into my account to alert him that I’m going to need a limit increase so I can urgently pay suppliers who had given me product on credit terms. Since revising the amount the business banker would not answer or return my calls for days. I then called his colleague who informed me that I have to go to a branch to make the transfer of that magnitude. When I got to the branch I was told that I must go back to business banking consultants as they are the ones that need to do this. I’ve been take back and forth I HAVE BEEN AT SANDTON CIFY BRANCH FOR 2 HOURS NOW and they are telling me they are busy verifying money that is in our business after I gave them documents they requested. I ADVICE YOU ALL TO NEVER USE STANDARDBANK FOR BUSINESS BANKING, I lost R2million potential profit already a few months ago because the business banker would not raise my limit after I asked him about 3 times already.
