I have been following this post and I feel really bad for you. Sounds like you have had some bad luck! Hope things get better...
I am from the Caribbean but have lived in the US and now Canada and I think I understand why suing would not be a "real" option. Out of those three countries I have lived in, the US is the only place I have heard of people suing over EVERYTHING. I was amazed. Not saying it is right or wrong but Im guessing SA is much more like the Caribbean or even Canada where you really just have to work things out without lawyers.
Anyways, good luck!
