You shouldn't ignore that amount. screw him left and right. this so called agents are eating peoples money for nothing.

Go to police and make him come there and money will come to you in no minute. Its clear that fault is at his side. stand up and get your money back even if its 100QR. and if you (anyone) who feel its small amount then please donate to needy. there are people in Qatar who are working for just 600. at least it would make them smile and pray for you :)
