Unprofessional customer service and incorrect information advised

Unprofessional customer service and incorrect information advised. I contacted the call centre to query why the last payment to my outstanding account was not paid which reflects a missed payment on my credit score. The call centre agent advised that the credit insurance was for 6 months meaning RCS only paid till July however after reviewing the policy documents and it states "Loss of Income Benefit: If You suffer a total loss of income, we will pay to RCS the monthly instalments due by You in terms of the Card Agreement: ∙ for a period of 12 (twelve) months; or ∙ during the remaining repayment period of the credit agreement; or ∙ until You are re-employed or are able to earn an income"
