Indigo Airlines — indigo staff treating travellers disrespectfully

Website: www.goindigo.in

I don't have much information but i have seen a video where a passenger was treated very badly by indigo staffs. As a viewer, i was very disappointed by this harsh and rude behavior from indigo staff. There has to be something where we could file a complaint against rude behavior as they claim that their job is to make passenger's experience safe and comfortable.
