NSFAS CLAIMING FUNDS I NEVER USED

NSFAS claim I am owing R61K which I had no acess to and have never used.They have handed my account to the attorneys even after I have furnished them the proof that the university (Central University of Technology) has reversed the funds to NSFAS. I have tried on multiple occasions to report this to NSFAS but they keep on ignoring my emails which includes the proof and focus on the amount they claim I am owing, now the account is in areas.
