[Resolved]  Indigo Airlines — ticket booked with meals

I have booked tickets ne624t for my parents (Senier citizens) in indigo 6e-6965 31/12 from bangalore to kochi. As a value added service, already purchased meal online. No meals were served to them in the flight. My parents are very old and really disappointed on the poor customer service the flight is offering. I need the complete refund for this inconvenience.
