TWO MONTHS TO REVERSE A CREDIT CARD PAYMENT!!!

I purchased movie tickets for the 14th FEBRUARY 2015 at Rosebank mall, however due to loadshedding was unable to go and watch the movie. As I paid by credit card I was advised to contact the call centre to request a reversal. I called the call centre on the 17th of FEBRUARY 2105, and spoke to an Unati who took my credit card number and name, she then informed me that the reversal will take 7-10 working days. I called back on the 4th of MARCH, it had still not been reversed, I called back again on the 24th of MARCH and was told by Andronica that Unati was not in and would get back to me. Unati did call me back and told me that the credit card reversal was STILL NOT PROCESSED and would be done asap. On the 31st of MARCH I called back and was told Unati was not in and would call me back, which she did not do. I left this alone till the 21st of APRIL and had STILL NOT RECEIVED A REVERSAL. I called to speak to Unati on the 21st of April and was told she would be in later that day. I left a message for her to call me back, which she did at 5pm that evening. She then took my DETAILS AGAIN AND PROMISED TO CALL ME BACK which she has not to date!!!
