Difficulty closing my Standard Bank Credit card (STILL BEING CHARGED)

Good day

On the 27th of April I got a call from Standard bank requesting me to make payment on my Credit Card as I have missed the previous months payment. On this day I told the consult that I plan to settle and close the credit card on the 28th of May and the consult said she will send me the settlement balance to be paid on May 28th. No other instruction was given to me other than to make the payment of R62 467.44 on May 28th. The morning of May 28th I made the payment and it reflected the next morning and had a balance of R0.00. On June 4th I decided to check the banking app and only to see I now have a balance of R511 which were all bank fees. I decided to call standard bank and dealt with a very rude and arrogant person who told me that I didn't follow the correct procedure to close the credit card after I explained to her the only the instruction I was given was to pay the settlement. After some words about her attitude I asked to speak to a manager but then the line dropped. On Monday June 6th I visited your Constantia branch and called your call center from there and spoke with a wonderful consultant (***) who said she will put a request in to have the bank fees reversed and my credit card closed. She told me It could take up to 48 hours but call me back once she gets feed back on the request. Today is JUNE 29TH and I have yet to receive a call back. The credit card is still active I have been requested to make a minimum payment of R25 before the 30th. This is completely unacceptable I have made enough effort to pay this credit card and to have it closed. I can't waste anymore money on calling you guys. I am very unhappy with how this is being handled. Something that could've been dealt with so easily. This needs to be resolved ASAP before I take my future banking to institution.
