I would not worry, that all sounds much like bluster. Also this organization is not to be trusted. They will skim of some of your salary each month, find ANY reason to deduct some of your airfare, and generally do things to annoy you and get you frustrated. Also, if you are placed in a school with a terrible FAO and disgusting accomodation, they will just tell you to be co-operative and that you signed a contract. They certainly won't stand up for you, as getting the fees from the school they placed you at is all they care about, you are expendable and don't even come bottom on their list of priorities. You are right, deal directly with the place you want to work man, not through this agency.

Good Luck,
