Indigo Airlines — Cheating regarding a job offer.

I was provided this opportunity for job offer for assistant manager and i was asked money for various purposes. I was asked inr 1750 for registration purpose which i gave, then i was asked for 6200 for documents verification purpose which also i gave. But then they asked for 14000 inr for interview entrance which i refused as i felt cheated as nobody does asks for this much amount just for an interview. Mr. Gaurav sharma the asst hr for indigo airlines had coordinated all this. When i asked for my money back, i was refused saying it cannot be returned whereas earlier it was refundable. I request you to please look into this cheat act and take a strict action against mr. Gaurav sharma and have my money refunded.
