Disgusting, Pathetic (non) service. Cannot answer a simple question

I need documents certified by a Commissioner of Oaths or a Bank Manager, specifically as requested by a third party. I asked on the Standard Bank Facebook page, via messenger as to which branch has a manager in my area, I even gave them a few branches to assist. The answer I received: Use the Banking App. Obviously the staff have no clue as to how to read. Once again, Standard Bank have managed to insult me - why should I expect anything different. As an ex banker, I would have been fired for that answer. Disgusting service, or non service. Very quick to charge me all sorts of fees but cannot give an answer .... like the call centre, customer service is not a priority at Standard Bank.
