[Resolved]  Indigo Airlines — lost baggage and indigo staff not doing anything about it

Being my seat 3e, i was boarded last and the overhead compartment was full and my carry on bag was taken by the head staff and handed over to the helper to place it at the backseats, i was told they will tell me where they have placed the bag and no one did, so i called them and they said they sent it down to put in cargo because of no space and asked me to collect at the baggage claim and when i asked for the receipt she said i dont need one, thats the last time i saw my baggage, reported in baggage services in bangalore and called them multiple times, they say they will get back to me within few hours but no one does. I cost me over 15k and they were not even willing to register a claim officially because they say the its my mistake to trust the airline staff, they could check the cctv cameras, spoke to the flight crew and to the ground crew but nothing was done or not communicated and the issue resolved
