Useless!!

I called in on the 7th for my credit limit increase - had a lovely conversation with Sithembele who helped me through eveything and told me my credit will be increased within 24-48hrs! Great...but, its now over 48hrs with no increase. So I called in to find out and get through to somebody else who says - sorry thats the wrong info,its between 3-5 days! Tried to get to a MANAGER to help me get clarity - well, apparently there are ONLY call centre staff and NO managers working there! I called the number 3 times, spoke to 7 different people, have been cut off twice and then I get told that they dont have numbers for your managers?? Really... Ive been a member for 12 years, and EVERY...SINGLE...TIME I need help with ANY banking issue - its always a problem, with no outcome and a very unpleasant experience! What ever happened to the \Treating the Customer Fairly\"??"
