From my point of view, it is a SCAM. They owe me almost 1000$ and they owe all the other teachers from the school I worked a few tens of thousands of THB. I don't understand why they're still working for this scam agency.
Maybe they are paying other teachers from others schools in time, but in my case... they don't even answer my phones/emails. I'm tired of asking for what's mine, I think I'll just pay them a visit and take something worth 1000$ from their office... maybe a computer.
