Settlement not recognised...

So I had a loan with Capitec Bank, I fell behind and a judgement was taken out on me. It was first handed over to VVM then NBA at a later stage. (I confirmed with an employee from Capitec and they confirmed that it was indeed now with NBA). Anyway I made payments till last month when I settled the account. I was given a discount on the said loan and paid it fully. Amount that was initially outstanding was R30 500.00 and got a discount to pay R24 400.00 of which I paid in full. I was the issued with a settlement letter for this, I sent it to Transunion for the Judgement to be rescinded since it was confirmed I no longer owe anything and my account was even closed by NBA. To my surprise I received a reply from Transunion that the creditor is saying the account wasn't paid in full so they cant remove the judgement from my name. Like where am I supposed to go from here? I am honestly tired of this account and I just want it off from my name at this point???
