Rude and unprofessional agent

I had a credit card with African Bank and after I was behind with my payments the account was handed over to Concept Discoveries. After some payments, I was told that I qualify for a discount if I settled the amount required. I was forwarded the letter confirming that the account closure request was sent.. When I checked my credit report the account was still existing and I called Concept Discoveries and they said that it will be updated on the next report. I didn't hear anything from the company or african bank until this week. I received a message that I still have an outstanding amount of work. I requested a call back and after waiting on the line for more than 15 minutes, an agent named Collette Mtshweni came on the line to assist. I told her what had happened and she said to me that she was going to log a call to request an account closure. I said am not paying the account though , asking a question and she said with an attitude "I said hold on the line because I need to log a call." when she came back on the line I asked again if I have to pay the amount and she "that's why I was logging a call and you will get feedback if need to pay or not" I then said to her you are not giving me a yes on no answer or explaining to me that the feedback will give me an accurate answer. She said to me" I told you that I need to log a call , so what didn't you understand ". .she said to me what else do you need assistance with obviously disregarding and disrespecting me. This girl was not professional and has an disgusting attitude. She clearly doesn't know what customer care is, I don't wish for anyone to deal with her disrespect and arrogance. So annoyed..
