Kabayan, Landlover and Spideman are right. Let the embassy work it out for you and they will tell you exactly what to do. For the money you paid, if the agency is based in Doha, you can get it from here, otherwise, you have to file complain to your origin and get it from there. Or, if you can afford to buy your own ticket, you simply quit your job by giving written notice (at least 3 days) to your employer and go back home. Your agency should be held liable for this mess and they should be the one to go in jail. Don't take matters into your own hands, let the embassy be involved in your case, this is their job.
