Worst service ever with no customer care

The service from SBSA is non-existing to say the least. Want to close my accounts, but it seems to be an impossible task, especially for my credit card account. I followed the exact steps, after I stood in a queue for 2.5 hours at the branch on a Saturday and several phone calls, however cannot complete this due to their ADVANCED security questions that DOES NOT INCLUDE QUESTIONS RELATED TO STANDARD BANK. You cannot proceed with what you want to do, unless you agree to answer questions not related to Standard Bank, which I find ridiculous and invasive. Questions include: do you have credit card with other banks / when did you move to property at XYZ / who is your current / previous employer? What does credit cards with other banks have to do with Standard Bank and who remembers when they moved into a place??? I am pretty sure that I have answered the questions correctly, however still get get it wrong. I am sure that I know what is going on in my life and not the information that they get from where ever. Now I have to go to a branch again. Luckily I know where a branch is, as the internet with branch information is also incorrect. The manager would have phoned me in a few minutes, after I asked to speak to the manager. Still waiting ....
