Standard Bank Insist on visiting branch to close accounts despite COVID 19

Due to Standard Bank's excessive fees, I am trying to consolidate all my standard bank accounts into a single account (which is also held by Standard Bank). Based on this https://community.standardbank.co.za/t5/General-banking/Closing-an-account/td-p/424469 they have removed the functionality from online banking but suggested one contact them via email. However, after no response to the recommended email, and contacting prestige banking directly, I've been instructed to visit the branch. Given the state of COVID 19, I find it shocking that a world-class institution is unable to activate a basic instruction like this without endangering the lives of their staff, the community or my family.
