Indigo Airlines — baggage misplaced by indigo airlines

I was travelling from lucknow to bangalore and i had a halt of 2.5 hours at new delhi airport on 14th october 2017. When i reached bangalore airport i found that one of my suit case was missing.
My baggage tag number was - 641618
Ct baggage description - bu22hwx.
Passenger name - manoj kumar
I am really upset with this kind of service from indigo airlines and i am facing this issue second time. I have lodged a complaint at bangalore airport and i am expecting an immediate response and i am expecting airlines to take care of passengers luggage with utmost priority to improve the service.
