ABSA's terrible customer service

I called the private banking call center to get my IT 3 B certificate as the online system only reflects 2 of my 3 bank accounts. The private banking call center cannot give you your private banker's (which changes constantly) contact details. Absa ask you the most ridiculous authenticity questions, such as how much your insurance debit order in November 2020 was etc. If you tell them you cannot remember the exact amount, you fail your authenticity verification, they block you and only your private banker can unblock you. Their bank charges are ridiculously high with no reduced rate for pensioners that have investments with them. FNB provide this. I am forced to keep a bank account that I do not use, because my personal accounts cannot be used as a sign on for the online system, it has to be a business account. etc. etc. I logged a complaint with the private banking Reference: C-***4. Was told my private banker will contact me. The next email stated the case was closed. I can write a book on my frustrations with this bank. If it would not be such a hassle to move all our bank accounts, I would have done that ages ago.
