Indigo Airlines — Loss of Check In Luggage

Address:

Mumbai

I, Belal Md Ali Khan, travelled by Indigo Flight no. 6E 5514 Mumbai-Patna (PNR-QNVJTD) on 17th of July-2021.
I check in bag Ref: 6E [protected] SEQ-0067 was loaded belt no.11 Indigo Mumbai T2 international airports.
My baggage has lost and almost 20 days are over, but I did not receive my check in baggage. I am really surprised to know how they handle the customer belongings in such a world class prestigious international airport. They even not able to trace my baggage. CCTV camera is there and individual customer details, ID, contact records are maintained, but even after that they are not able to trace.
They are telling me for compensation of 5000 INR for the lost baggage. But I have lost more than 25000 amount of content in luggage.
