Standard Bank's silly games

I've been incorrectly charged for a credit card statement (another story) and requested a refund for ONLY R25.00 . I phoned card division and can't get past their silly questions and was told to visit a branch because I've been blocked. The questions have nothing to do with Standard Bank and who knows what answers they expect from their unsubstantiated 'externally sourced' questions. The complaints person at Standard Bank won't register my grievance because it's banking policy, instead I got a patronising lecture on how important security is to them. This Standard Bank is a dumb policy and maybe one day when I get through to you, you'll refund my R25.00 into my new FNB account.
