Why debit my account for a settled and closed credit card ?

From the 25th of March till today I have big problems with Capitec bank , i went to CapitecRequested to settle and close my credit card, consultant at rosebank gave me the amount . From paying that Capitec made me run like a headless chicken as now the credit card would not be closed as all of a sudden I was owing . To cut the matter short . I went to Capitec everyday at rosebank mall . Last week one consultant called the branch and finally I got an sms that the credit card it’s marked for closure and they won’t debit my account , on the 25th April R25 was debited , today I received an sms saying R25 will be debited on the 25 of May , I am now owing R40 , I don’t know what to do now . I am very disappointed and hurt by the way Capitec do things . Why debit my account for a credit card that credit was approved after the consultant gave me the wrong amount to settle ?
