Fraud & cheat of money

Sir i m Nirmal dubey i m a seaman. I came in mumbai in 15 oct. 2016 for job placement in shipping company. I met a placement ajent mr. Sazid khan & mr. Ashlam khan owner of Alpha star marine services gala no. 528 5th floor BMC bldng near dreams mall Bhandup w. Mumbai -78 . He said to me that you get job in 1 month with best salry 550$ pm in best shipping company post as an oiler but you have to pay 4 lacks rupees. So i paid 4 lacks. But they not placed in promised time . i waited 5 month in mumbai then he placed in a shipping company through casablanca shipping pvt ltd mumbai. He promised me that company pay 550$ pr month with 9 month contract and ship rout malta( europe ) to lebnan But not give me any contract latter then i ask about contract latter . He said to me when u join tha ship then shipping company give you cotract latter at port . I joined oil tanker ship 25 march 2017. At oman port .Next day i asked about contract latter to captain of our ship . Captaion said to me that i asked to company about contract latter but not give me contract latter till 3 day and no reply to company. Ship go to sail oman to egypt. After 22 day ship reached egypt but not give me contract latter. After 4 days company say to captain . Ship not going to malta. Ship will go to Libiya. Libiya is high risk area due to reason of isis. Oil import baned in libiya. But compny say to capatain . Ship will go to libiya for illegel operation and load tha ship in night with shut down tha lighting and navigation system than carried tha oil to lebnan. This is high risk job for all crew. So all crew not ready to illegel operation all want to sign off to ship. Then all crew return to our country After reached mumbai 2 may 2017 than i met to our ajent and told full story. But my ajent said to me that not my responsibility and not ready to return my money. So pls give me advise about how to get return may money . This placement office not rasistard and not have any authaurity from shipping this is totly fraud and fake office. So pls give advise how to take action against this office and how to get return may money. Thank you ....
