Standard Bank Credit Card division security questions

Phoned the Standard Bank credit card division to have my credit card authorised for an overseas trip, was told that they had to ask security questions which I am more than happy to answer, they then asked +- 10 odd questions and I was then told that 1 of the answers to the questions was wrong according to their system and that I had to go into a branch or phone back in 24 hours, when I queried this as I know what is actually going on in my life with my accounts etc. I was put on hold while the assistant asked his team leader the way forward, he then came back to me and told me that they still couldn't help me. The service in my opinion is appalling and I will probably take my business elsewhere.
