Seems you've had a fairly awful experience. Good to know that you're out and let's hope for the welfare of the remaining teachers.

I guess hindsight is a wonderful thing and let's hope that potential teachers will not even consider gallop in the first place. However, when initially presented with a dump of an apartment and a contract different from that which was agreed upon you should have walked away there and then.

You mention an agency(maybe a recruiter) in your post. What's their name and what did you pay them for?
