I have emailed the SA CAA without success...
That should be a clue as to what your problems are going to be...
A work permit will be needed before any licence issues will be of any use to you. And if you think that a lack of success in replies from the SA CAA are a problem, that is just the start! I know people who were entitled to residents' permits there but the whole process to get through the paperwork was taking so long (many, many, many months) that they gave up on the whole idea and no longer live there. Good luck!
