Please close my accounts

I have been trying to communicate with the business banking department to close an account since the 4th of May. I have been very unsuccessful with this, I do not understand how you do not have any simple way for someone to close a business bank account, nor clear instructions on how to do so anywhere except to email this address. Since it has been so painful to close this account (which i closed because i opened another account with capitec) I am now requesting BOTH my business bank accounts be closed, It is very stressful knowing that I cannot get help for simple matters and I would rather continue on with standard bank as their private bankers make things very easy without me having to manage phone calls (I am a small business owners busy on site, answering calls does not work for me) so if communication can only happen via calls and I cannot get help via emails then this will not work for me. I also refuse to pay any more bank charges for June, I asked for help 3 weeks ago.
