Indigo Airlines — TSA lock missing from my Check-In baggage

BLR to PUN

I had a external TSA lock (not fixed with the bag). When I reached hotel and wanted to unpack found the lock to be missing. I raised this concern with the IndiGo team and they say, these checks are to be done at the airport itself and not later. They also say that, this has to be complained at the Airport and not to them.

According to me, this should be taken care by the Airlines and not the airport.
