Standardbank no help for their client

In the first week of January 2015 I reported a ********** transaction on my creditcard. It is now SEVEN MONTHS later and NO progress have been made by Standardbank. I have phoned lost count how many times, no person knows what the other one has done and needs to hear the entire story every time, with another ref no. I physically went into the bank 3+ times with no help, they simply put me on the phone again. After spending so much money on phone calls where I hold on for 30 minutes and then another 30 minutes going between people I am now fed-up with this terrible terrible service. What can be done to sort out this mess? Where does a client of a bank go to sort out a problem if their banking institution just does NOT help them or attend to a problem on the account????
