Fraudulant Job offering

Reyansh Kar claiming to be an Ex employee of Spice Jet and currently working with Lufthanza posted an Ad in Quikr to provide Jobs in Lufthanza as Ground Staff and instead would take 20000/- per applicant and confirm the appointment on the 22nd Sep 2014. Me along with a collegue Vikram S.N and Rahul P were told that jobs would be granted for sure and kept in dark for about 2 months without any documented assurance. We were called at his residence in Panvel and money was taken in cash with a verbal confirmation that we would get the offer letter in 7 days which would also advise the date of joining in lufthanza. we have his Face book profile saved with us which clearly indicates him being dressed in an commercial pilot attire to make it authentic. Post some direct questions related to offer letters, appointment dates, induction day, training venue he has decided to abstain from answering since there were no plausible answers he could provide. Today which is 12th November 2014 his cell has been switched off and not reachable. With deep regret we have to believe that our hard earned money has been lost especially during times of our unemployment. Hope we could get some assistance in knowing the way forward to get a grip towards this situation and also further prevent any more citizens in india from falling prey to such frauds.
