Qatar Airways — Baggage missing

I landed in Chennai on August 6 2022 early morning 2.30 am. I found out that both my luggages didn't arrive do I filed a missing bag report for the bags as soon as I found out that my luggages were missing. The agent said I could call their Chennai baggage claim office if my luggages didn't arrive within 12 pm the next day. On 7th August, one baggage was delivered at 3 pm, and the agent said that the other bag is on the flight from Doha to Chennai and should arrive on 8th August (today). When I called again to enquire this morning, they're saying that they do not know where my baggage is and that they've not received it at Chennai. This is ridiculous. I've been sitting here without clothes to change just waiting for my bag to arrive. I have valuable materials in my bag so I need my bag, otherwise I'm going to take some serious actions. So far, no updates please look into this
