Yeah, I thought as much. If you did you would understand just how out of order that person was to be taking that tone with the VC.
NSFAS is independent from the University, they are an institution with their own management and board and they are the ones who are responsible to make sure that the money that is due to the students is paid, not the Vice Chancellor.
NSFAS is not accountable to the VC or the university, they are accountable to the Minister of Higher Education. If the VC gets involved it is assistance, it's not their job, so if you find yourself frustrated as a student you certainly don't call the person who is helping you a liar and expect her to respond in kind.
The blame for not paying the NSFAS allowance lies squarely on NSFAS, not the VC or anyone. You should at least try to put an effort of understanding how things work before you open your loud, know it all mouth.
