write a letter to the company saying that u are going to complain the labor department in USA and IMMIGRATION IN CANADA if they didnt give your money back

call the immigration in canada, and expain them your situation ...........they will give u advise .......also called labor department here in USA, AND ALSO CALLED BETTER BUSINESS BUREAU HERE IN USA AND THEY WILL GUIDE U TOO ...........

if nothing seems to work, go through a lawyer  ,but normally government will help u out .......

if nothing works out still, either keep quiet or buy a ak47 and shoot all the fradulenet dhotis .....or gather a few nepali guys and break their heads the nepali way ......(i am kidding_) ............u will be okay and wont have to resort to violence.......govenrment will help u out ..........go legally !
