DAY LIGHT ******* BY NSFAS

Bad experience where they contacted my former employer for payment and I had no choice in negotiating lower payment as I called and emailed to negotiate. I paid until the last payment. 6 years later they called me telling me I have close to R2000 rands outstanding, I tried by all means to communicate to them and they just shut me down without any responses. I even asked them to setup a meeting with directors and education minister so that they can maybe explain to me but they just kept mum on me to date. Can I please be helped on this matter. My email address is ***
