Just a fraud

I have been cheated by this company. I have been waiting for very long time after I submitted the application form. I have sent emails asking and complaining but no one reply me. When the 45 days 'deadline' come, they only gave me an offer of 2 months working in Beijing although I have been emphasized several times that I could only work in Shanghai for one month. I asked for refund several times but they replied me that the $300 USD is not a deposit but a application processing free. They can just ignore their terms as well as your application. I had high expectation at first but what I leave now is merely rage and disappointment.
