Air India — One of my baggage is missing.

Me and my husband had boarded flight of Air India on 14th of april 2024 from mangalore to Mumbai and on 15th we had a connecting flight of Air India from Mumbai to Delhi and Delhi to Amsterdam. We had altogether 5 baggage and the staff of Air India informed us that we cannot carry all the baggage as we were allowed only 4 but then we paid for the 5th baggage amounting to 15000 rupees but as we reached Amsterdam airport we received only 4 baggage and one was missing and we filed property irregularity report and its been 3days we havent heard back from Air India and being in Netherlands I'm trying to contact Indian Air India number but its not even getting connected i tried everything from my end and its all in vain i have mos important stuffs in that baggage but still they are not helping us out and even i paid for that baggage!
