So it is nightmare.
The real reason you can't operate in ZA is Empowerment, and what Google probably ran into. They can only own 49% of the business the start. They must find an empowerment partner (which means some black people, but they have no money so you have to give them their controlling 51% share) that happens to be a friend of the ANC (not a documented requirement, but I did mention corruption). So they will siphon funds out of the company, but if you have the right ones, you can win big government contracts such with the bailout money they keep getting.
The place is a banana republic - Live there, enjoy you cheap labour, great food, amazing geography, the wildlife, your personal security guards and inexpensive servants, but don't reside there and keep everything in another currency.
