Unfairly declined for registration

I went to the Florida campus yesterday as my application of admission was ignored from 17 September 2021 last after submitting my results from damelin correspondence college.

The ladies from the faculty of Accounting Sciences said my qualification does not exist as Damelin correspondence college didn't register it with the Higher Education and training, and they emailed me a declined letter that I couldn't register for the course I wanted to do,

It has come to my attention that the course I did was de-registered by the Higher education and training on the 30 June 2020 due to less number of enrollments and I enrolled for my course in 2017 and got my qualification in April 2020,

I believe my qualification to be valid for me to be accepted at Unisa but the unisa staff didn't check all that information
