Indigo Airlines — indigo staff was heard abusing another indigo staff

On 4th august 2019 i reached hyderabad airport to catch my flight indigo flight number being 6e 683 whose departure time was 1030 am. I have got the seat 16a and my spouse and got the seats 11f and 21c. While we were standing in front of the check in counter we could see a coloured lean guy wearing tie apparently in his early fifties positioned behind the boy in the check in counter near the belt obviously overseeing the handling of the baggages meant to load in the flight. He was heard saying “ where is lashkar? “. This was a slur expected to assess somebody. The boy in the counter who was putting the stickers on our baggage leaned on our baggage to turn his face back to give an appreciating wider smile to the guy who used that slur against one of your staff members. Then that the supervisor increased his voice pitch calling the name “ sameer “. There i saw a bespectacled young boy responded to his call. This kind of contemptuous behaviour from your staff is deplorable. Sameer did not apparently hear the slur as he was busy with his work
Kindly take measures to preempt recurrence of such misdeeds
