PATHETIC CREDIT BUREAU QUESTIONS VERIFICATION SYSTEM ABSA USES

I have had a problem linking one of my credit cards to my on line profile for quite some time. I now see I have two different credit card numbers with exactly the same balance linked, but as said different account numbers. I try to get this resolved but now ABSA's stupid 4 questions system failed me!!!!! I cannot remember a Telkom number I had at least 16 years ago. I cannot remember exactly how many years I have had a VODACOM contract. What stupidity is this. Now nobody can assist me because I failed these utterly stupid questions This is ABSA's mess not mine that they cannot resolve!!
