-- I was living in an apartment with a bathroom that leaked from the floor, the toilet, and the sink.
-- The AC didn't work.
-- The Internet wasn't connected.
-- I couldn't close the front door because it was jammed.
-- I couldn't stand in front of the bathroom mirror because the water heater was in the way.
-- The walls were severely stained. The bedroom and the bathroom were extremely ill lit.
-- This was my third company provided apartment and none of them had a kitchen, even though the contract specifies a kitchen and even specifies a fridge and a microwave.
-- I had to buy my own heater, rice cooker, lamp, extension cord, etc, even a mouse for my offce computer.
-- He wanted me to contribute to the Buckland Facebook page, but he wouldn't pay for a VPN, even after he told me to use a free VPN and I informed him all the free VPNs are blocked.
-- His Chinese course teacher agreed to tutor me a few hours a week in her free time, but then he told her she couldn't tutor me unless I enrolled in his Chinese course.

O和de a r, it does sound like you have a real grievance, as long as you did all the standard checks before you agreed to work for them? Did you get detailed photographs of the exact flat you are now occupying? Did you speak with a half dozen other teachers past and currently employed there? If you didn't do those things i hope you just grinned and beared it.
