RCS and Edgars is pathetic

Good day I Purchase from Edgars beginning of June 2023. End of June I made the full payment on my account in the Edgars store. I started receiving message that I must pay my account. After numerous calls and emails. I literally send it to Edgars RCS , RCS collection centres the proof of payment. Every time i followed up . Somebody refered it to somebody else. They actually lost my payment in the system I send them proof over and over. Even spoke to the supervisor. I Requested one of the Regionals or Directors numbers as I stated in my mail. It seem like everybody pass the buck but nobody is prepared to do something as this is affecting my credit score. I never missed a payment on any account ky whole life. And now it show on clear score that i missed 3 payment and a balance of R4 . I again send messages and cc everybody. Now it is end November. Nobody came back to me sorted it out. Can somebody please give me the contact details of somebody that can assist. Edgars as well as RCS do not care that the ruin your credit record . And the service is so pathetic. Engela Wasserfall ***
