Closure of Nedbank Personal loan - no assistance!!!!

My Nedbank personal loan account was handed over to T J Moadi Inc. I have however paid it in full the 25 October 2019. To-date Nedbank has not updated their systems, even though it is pass the 20 working days. I have sent numerous emails to TJ Moadi for assistance - they are not responding. My ITC has not been updates. Nedbank is unable to assist. WHO must I contact for them to update my profile. This is affecting my credit record. I had to sacrifice alot to be able to settle my Nedbank loans. The least they can do is update my their systems. Every day I do follow-up's with no response. can someone urgently assist!!!
