You can't do anything about..it is true that company will provide a 2-way ticket as what mention in the contract "BUT" is not mention there which airlines right???so, it is the discretion of the company to give you the lower price of the ticket because they want to save money...I do hope you understand it..Even if you go to labour court, you can't win unless you have a very influential lawyer but it will cost you more money...If i were you, just keep quite, take the flight which has been offered to you and when you are in your country, have a deep though if you still want to comeback or not, otherwise go to another country and after two years come to Qatar wherein great opportunities are still around...good luck....
