NSFAS - Not coded

I had a dual registration query which I was not aware of last year which I advised NSFAS about and I was advised to send proof of registration for the correct institution on the 7th of June last year to dualreg department and I did. They still paid UNISA instead of DUT and as a result they have not paid the correct institution and I have not been coded to receive funding for this year either, despite logging another query 6 weeks ago. The worse part is, no one knows what to do to assist me and all I'm advised to do is wait, but I have been waiting since last year when I sent proof of registration for the correct institution which is DUT.
