Also if you can locate it file a complaint with office of procurement. They are required to investigate ANY complaint that comes across their desk. And yes foreign teacher scamming is under their purview.
They try to rip me off and are very nasty. I am stranded in a foreign country. It was payday yesterday. Today the boss says she is too busy eating lunch today to pay me. My hotel is paid until tomorrow. Then, I will have limited funds and have no money soon. Payday is the hard part with these companies. They suck. Their name begins with an S and ends with an R. I wrote all my students and told them to tell the company to pay me. It used to work. My students parents hate this company too. This company is a nightmare. They lie, cheat, and steal. I am writing the PSB now and reporting them for non-payment of salary. I think these Chinese people in my company have no pride, dignity, or self-respect. My company certainly proves that, and they are based in Beijing.
