You will need to contact the National Student Financial Aid Scheme (NSFAS) in South Africa directly to find out your status (application status?)
This is the link to the NSFAS home page:
Currently, at the top of that web page you should see a notice for 2018 funding applicants.
If you scroll down that page, near the bottom of the page you will see a column headed with the word STUDENTS. Click or tap on the Student Support link. You may have other questions listed in the questions, with answers there.
By the way, your question landed in the Fixya.com category of Computers & Internet and not the Financial Aid category.
Fixya.com is not the best website for asking your questions about university financial aid or universities in South Africa. It is intended as a website for asking and answering questions about repairing _things_. If you have a public library (a library funded with local or provincial government money) in your area, I recommend you ask your questions there . . .either in person or through a telephone call.
