Indigo Airlines — Missing luggage and rude behavior with my wife by indigo staff

My wife today[protected] went to Lucknow from Delhi via indigo flight 6E 3457 with 2 pieces of luggage (a bag and a suitcase). When she landed at Lucknow airport then she was very RUDELY INFORMED by the indigo staff that her suitcase was not boarded on the same flight and that she has to COME AGAIN to the airport at 6:30 p.m. to collect the suitcase. I personally called Indigo customer care number [protected] and was transferred 3 to 4 times before some guy answered and talked to me very disinterestedly and rudely and told me that my wife has to go back to the Lucknow airport to collect the suitcase and that it will not be delivered to the home address. When I insisted then he forwarded my complaint very reluctantly like the government people do.
My wife was given a number of indigo staff at Lucknow Airport – [protected]. She again spoke to my wife and to me very rudely to which I also have the phone call recording. Nobody at Indigo is responding to our problem and on top of that we are being taken for granted we are consistently being treated very rudely.
I am very hurt and upset with the indigo services and my entire family and friends have decided not to fly with Indigo airlines ever again. Indigo has outrageously told us that they will not in any scenario, deliver the luggage home (which was by the mistake of Indigo staff Delhi themselves not boarded on the same flight as my wife). It sounded like an open challenge.
I want to be compensated for this blunder and rude behavior with my wife.
