Bank's incorrect information hinders my ability to transact

Your security question system does NOT work. Every single time I try to talk to anyone at Standard Bank, I'm told I've failed the security questions. Which means that I am never able to get assistance from Standard Bank, and it is getting really old. At this stage, I want to move ALL my business to Investec, with whom I also have an account, and where I have a personal banker who actually knows me. I can't keep playing this ridiculous little game with you. I am a CA(SA), an ACMA, and a CGMA. I have no reason to lie, and I most certainly haven't. I can't help it if your systems are outdated or you have old information or you draw incorrect information from the credit bureau. Because you also refuse to tell me where I have 'failed', I can't correct YOUR incorrect information. I don't know whether to send through a contract from my new employer or a municipal bill stating my address or a statement from the clothing retailer you seem to deny I have an account with. I am trying to report a *****ulent transaction on MY account that has MY money in it, and you are denying me access. I asked to speak to a team leader (at 16:20 on Wed 13 March), and was promised, after holding for a very long time, a call-back within 5 minutes. That was more 2 hours ago. You need to sharpen up your customer service skills or face losing long-time customers. After 30 years with Standard Bank, I am no longer impressed.
