Credit Card fee dispute and *********** staff that does not know products

I called in Friday evening to find out about my Credit Card. I had it for months and was never charged the R50 monthly fee, I saw online thereafter if your credit limit is R600, they waiver the fee. All of a sudden after speaking to her, they charging me. What disgusting money hungry people. I told her to leave it as is, because she didnt even know their own products. She told me you dont earn interest on a positive balance on your credit card, when it clearly says so online. PLEASE train your staff...After I get my Live better rewards on the 10th, I want my accounts closed with immediate effect. I will not incorporate myself with a bank like this, charging R50 on such a low credit limit. Its day light *******. What a coincidence after speaking to her, you charge me the next day.
