Northlink certificates waiting too long

I was doing a Wholesale and Retail Management course at Northlink College, Parow Campus from Level 1 to Level 3. I started in January 2016 till April 2019 and I have never gotten any of my certificates. The only thing we got were the statements of results and that was it. I have been to the Campus a thousand times and the only thing I have gotten was that they are still waiting for the W&R Seta for the certificates. It's been 6 years waiting and I'm tired now. All I want is my certificates because workplaces wants certificates not SOR. I tried writing emails but I haven't gotten any response so I don't know what to do now.
