Write a formal complain on paper with all prrofs.. visit local poloc station amd tell them you want to register a fir.. usually they will try to avoid you and wud tell ur fault.. and would refuse to register FIR…. You keep insiting for it… lastly they would call the guy with his own mobile and will tell him to return ur money or else they will regisyer FIR. This is my personal and recent experience.. somehow aftr 2 mnths of complain and totalaftr 6 months got my full money back
