Nimble group

Im totally disgusted in the Nimble group I had a mix telematics account I cancelled because of bad service mix telematics is showing as a open account on my credit profile with a balance of just over R5000 nimble goes and list the same account on the credit bureau with the same reference number for a amount of over R6800 firstly I would like nimble to confirm my debt with the relevant chain of debt secondly I want that account removed from my credit profile as per the law you can't duplicate a account as the mix telematics accounts shows a open status so the duplicating account is a inaccurate reflection of my credit commitment and I don't consent to inaccurate credit information being shared I want a way Forward or I'll take this up with the nca you can't just duplicate accounts as you please.
