Appalling ******** debt

The Nimble group - Fochini clothing account number *** opened 25/082006 and was at an amount of R24 503.00, limited amount. I had always paid account above satisfaction but due to my divorce in 2016 I had paid a settlement amount in full and closed the account. Yet there had after account was settled an amount of R242.00 outstanding which I had later went into the store and had paid whereby the store employees had called the department to confirm payment. Since this occurrence in 2016 I do not have supporting documents but this should be on the credit record. Recently I have app**** for a store account to my surprise and dispute that this dispute is still on my name which is not allowing me to have any credit record this is absolutely appalling and I kindly request thos is removed with priority of my name as I want to move on with my life. Really upset person
