Unnecessary Line of Security Questioning

Was put through to credit card department after possible ***** issue which was discussed with ***** department. After concluding initial issue, i informed of sms notification issue i've been having for months, whereby any amount received to credit card account will always show a balance of zero . Was told that i should take matter to cellphone department , who then told me to take matter to credit card department. Once again re-explaining issue, was told to answer a few security questions. One which was, how long i have had my Woolworths account. How is anybody supposed to remember how long ago they may have opened an account ago. I am 43 years old and expected to answer a question like this, which only ABSA is keeping track of the days with their system. And instead of asking a different security question, the entire matter I had come to them to be resolved, was now completely halted. What are gonna ask me next, what I'll be having for breakfast the day before I die? How about what race and gender one of great great grand child will be?
