blocked my credit card for fica documentation

Standard bank blocked my blue bean credit card without informing me! I was embarressed @ the POS when my purchase was declined. When I queried it, telephonically, they told me to take my fica documentation to my nearest standard bank branch. Please bear in mind that it took 50 minutes on my landline with them! I did as they requested, not once but twice, and they still never sorted out my query! I even tried to log a complaint with the branch manager @ kromboom branch on the 18/07/2014, but he/she wasn't available, so I spoke to the second in charge, who handed me over to a consultant, but still no luck. They temporary unfroze my account, but now on saturday 15/08/2015, they blocked it again! I am flabergasted by the pathetic service that I'm receiving from them as I'm a loyal client for plus minus 10 years now already. If they don't sort out my query asap, I'm going to take my business elswhere!
