Aside from your dodgy English, your post is lacking in substance. So, I'll ignore its contents. That said, the name of that school implies it's a language mill/training centre type of operation. That kind of set-up is best to be avoided in any case. If you'd done your homework in the first place, you'd have found that out, and wouldn't have gone there. My last point is that breach of contract due to a family emergency will result in a financial penalty for the foreign teacher, and quite rightly so, according to the conditions of the teacher's contract that cover that type of situation, of course!
