Cheated by a recruitment firm in Thane

I got a call from someone who said my CV has been shortlisted for HDFC Bank and told me to come for the interview. When I went there they took my interview and also took Rs.2000 from me. They told me that my next interview is tomorrow after that I left. Later when I called them their phones were switched off and I realised that they cheated me. This is not right to cheat innocent job seekers like this. What happened to me can again happen to someone else which I don’t want. I have all the proofs against them along with their numbers and receipts etc. Please help as I’m in alot of stress because of such people running fake agencies this should be stopped.
