RCS Not adhering to debt review processes and requirements

I went under debt review June 2022. During that time RCS agreed to the payment arrangement made with my debt councillor and they approved it. My situation changed and the court cancelled the debt review beginning March 2023 as my financial situation changed for the better. When checking my bureaux RCS shows that I am 7 months in arrears and they handed me over to Anthony Richards and Associated. I agree I as 2 months before going into debt review, but my payment terms were restructured. I called them and they said me basically "yes we agree that you pay the lower installment and we accepted the adjusted payment terms, but guess what you needed to make the full original installments and not the agreed payment terms as per agreement (in writing) with my debt councillor" as per the team leader that spoke to me and did not give me her name. They also refuse let you speak to a manager. The are breaking the National Credit Act and actually does not give a damn about their customer and what is right.
