Indigo Airlines — money was stolen from my checked in luggage

I am feeling very disappointed to share this for such a renowned company like indigo that our checked in luggage is not safe.
Yesterday i travelled from nag to del by indigo flight with pnr ze4i9d. When i entered in airport my wallet has 2600 rs.in it. I kept dat bag in luggage. Before reaching home i found that my all cash was stolen from my wallet. I complained regarding this to customer care and they denied to take responsibility for this incident. Worst service by indigo. Take it as my complaint and refund me back my money.
