Nsfas ******** old students

I paid off my loan in August 2019 and got my nil balance letters, yes i have 2 of them. But tomy surprise, that R0. 00 balance has accumulated an interest of R3757 in September 2019.I do not know who to contact for help. If anyone has Blade Ndzimande's contacts please assist or if one has the NSFAS finance department contacts, please assist me. I feel pity for new students who are enrolling in Universities and Tvet colleges through NSFAS, they do not know the kind of ******* the organization is.

I want to be free from NSFAS
