What a faulty system

Everytime they call or I call they ask security questions ....all good for security. But whenever I awnser to the best of my knowledge ... as obviously i know myself and what i have..... it fails.... how can this be... Must i send the system a photo or something of me? I am now tired Absa has failed to meet its customers needs by having a faulty system..... Absa has failed its customers by not sorting it our. All around Absa has failed in my eyes What bank system tells its customers they not who they are?
