Indigo Airlines — Veg Meal mentioned in the ticket but not provided

Address: New Delhi, Delhi

Dear Team, I was travelling from Mumbai to Delhi via 6E 184 leving from Mumbai at 6.20 AM. My Airline PNR was S2RD5V. We had a corporate booking and had veg meal booked but the Indigo employee talked very rudely and told us that it was not reflecting in his system.His name was Vinod and he refused to take the complaint as well. Kindly let us know how we can get a refund of this and how we can take an action against the Indigo employee
