Closure of Credit card

I'm so irritated now, I can give a crocodile a french kiss. On 23/10/2017, I called WW financial services & informed them that I would like to close my credit card. The lady informed me that because I used my card the previous day she won't be able to assist me in giving me an accurate settlement amount & that I would have to call back 48 hours later as the charges has not been updated on my card. That I fully understood. I refrained from using the card again & called them back exactly one week later. Spoke to Asanda on 30/10/2017 at about 08h47 & requested the settlement amount for my credit card. The amount was given to me & was explained to me that if I eft the money from my account, I should wait 48 hours, make another call & it will be closed. That I fully understood. I eft the exact amount as given to me by Asanda to the cent. However two days later after the eft, I called WW financial services again & spoke to Lavern & requested to close my credit card. She then in turn informed me that there is now a ballance of almost R200 on the account that must first be paid before closure. THAT I FAILED TO UNDERSTAND!!! She told me that because I used the card on 30/09/2017, it only reflect on their side now. Furthermore I now incurred other charges associated with this card. I tried to talk to the Supervisor or someone who can assist me in this regard but to no avail. I WANT TO CLOSE THIS ACCOUNT BUT GET NO JOY OR ASSISTANCE IN THIS REGARD FROM WW FINANCIAL SERVICES AND NO ONE CAN EXPLAIN TO ME WHY THE EXTRA EXCESSIVE CHARGES. I PAID WHAT I WAS QUOTED AS A SETTLEMENT BUT EVERY TIME I CALL I'M BEING CHARGED NEW CHARGES.
