SA has been performing shitty for quite some time now. There was nothing to suggest that they will win as their batsmen have not been performing as expected by them. The score was just 203 and they were not able to chase it, imagine how bad they have batted. You should have checked their previous performance before putting money on them.
Gone are the days when South Africa was considered as competitive as the big 3 teams. When players like Alan Donald, Shaun Pollock, Jacques Kallis and Lance Klusener were playing for them, they were the toughest side to beat. But times have changed and due to quota policy many of the promising white players have emigrated to other countries. And some of these players (Neil Wagner, Devon Conway, Marnus Labuschagne, Colin Munro, David Wiese.etc) have become the backbone of their adopted teams.
But a part of the reason why South Africa performed so poorly lies in the pitch. The surface that was prepared for the 3rd match was close to unplayable.
I agree that the "Politics" have ruined South African Cricket, because people are not chosen for teams based on their performance or skills anymore, but just on the color of their skin.
Some might say it is reversed Apartheid, but we have to agree that the previous disadvantaged people also has to come through to compete at the highest levels and some of these people are very skilled and capable to do the job... the problem is.. too many are chosen now, that are not ready for that level of competition and Politicians are only focused on numbers and ratios.
The excuse that the pitch was unplayable, should also have been a problem for the other team.. so it is the team that adapt to the conditions of the pitch ...that will win the game.
