Nedbank loan *******!

Hello Peter

I am so frustrated with Nedbank, 0n 2013 August I took a 100k loan with them on a 60 months repayment term. I only started paying my monthly installment September 2013. I had some payments missed in between however ended up negotiating with them how to pay my arrears. My monthly installment is R3420 I decided to add R1000 every month for arrears. On the 28 of May 2018, I Called the Nedbank accounts requesting them to give me the total amount of Arrears as well as interest. A confirmation sms was sent to me that my Arrears are R19 880.93. On the 29th of May 2018 I paid my arrears in full to bring my account up to date, Which the Nedbank customer services confirmed. However when calling the Nedbank customer services to get my balance. I got a shocking R24k outstanding with only 3 months left on the contract. It didn't make sense and the lady by the name of Thato can't explain how did it even got to that amount. She is advising me to get a statement from 2013 till to date. So that I can do calculation as how my balance is 24k. I have requested the statement and I require someone from the accounts department to explain how is that possible that I paid up my arrears with interest and the balance doesn't correspond with the outstanding loan term. I suspect that there is human error or someone didn't do his/her job. Now they want to make me accountable for their mistake. I will take it up with credit ombudsman. I don't have an extra 14k to give away just like that.
