Standard Bank's ********** caller authentication process, customers fail their own questions!

Call centre authentication process a waste of my cell phone all and my time! Standard Bank new call centre authentication process is terrible, and such dated questions they ask, when the client themselves don't even know the answer, and fail their own authentication process. The questions date back to the 1980's about companies they may or may not have had a silent partner shareholding in, and they require exact dates/titles etc. I phoned asking to speak to the N1 City Manager, and they can only email him to phone me back. Why can't the customer email the request, no they say, only internal email. One single number for Standard Bank, and takes 20 minutes to speak to a human being, and then the whole authentication process of another 20 minutes takes place. Seriously, Standard Bank, this irritates me to the point, that after 35 years of loyalty to Standard Bank, this is now my tipping point, no more! You should be able to flag a question that a customer has repeatedly not answered, because they don't know, but have answered others successfully, and the Bank has established authenticity of the customer.
