Aquifin contravention NCR

I am writing to formally dispute the information reported by Aquifin on my TransUnion credit profile . The account in question was originally under Capfin, and the debt associated with this account was written off and subsequently sold to Aquifin. However, Aquifin has reinstated this debt on my profile, which is in direct contravention of the National Credit Act (NCA) and National Credit Regulator (NCR) guidelines regarding the reporting of sold and written-off debts.
