Capitec Bank ******

I had a credit card with capitec Bank after being on debt busters I canceled my contract with them due to balances not going down. On September 2022 I contacted the capitec debt review department to send me my balance which was R2850 and I arranged with them to make that payment on the 14th of October 2022 which I have paid and sent out proof of payment. But to surprise when I asked for my paid up letter after 5 days the department sent me a balance of R1650 that I need to pay again. After I've wrote to them several emails that I do not have any balance on my side even on my bank app it shows that I have fully paid up my capitec credit card amount. Even today I haven't received my paid up letter they don't even respond to my emails at all I checked my credit report after a month it still says my account is active. Capitec I want my paid up letter with a immediate effect I do not owe anything.
