Air India — misplaced your baggage

Address:

#311,3rd block,59th cross ,Rajajinagar,Bashyam Circle, Shanta Krupa, 560010

Our flight from rajkot to bangalore via mumbai was on 2nd
July 2019 was at 5:15 pm ai656.. That was delayed and deprted from rajkot at around 7:30 pm.. We had checked in our bag at baggage drop (1 sutcase maroon colour hardcase of traworld brand medium sized) upto bangalore in rajkot..
Since our 1st flight (Rajkot-bombay) was delayed we missed our connecting flight (Mumbai-bangalore)...
We approached air india officials.. They gave us the next available flight to bangalore ie on july 3rd at morning 6:15.. And they also took our luggage checkin tag for searching our bag.. We waited from night 10 pm to morning 4:30 am.. They dint get outr bag and the officials in the counters also vanished.. After that one senior person sitting in the counter whose answer was "i dont know when and what there is mess everywhere" informed us that our luggage will reach bangalore as we had checked it in for bangalore and the tag on the luggage was till bangalore.. So we had to leave to catch our flight..
Its been 48 hrs now... Baggeg service officials in bangalore are not responding.. We have no idea whats happening
