Air India — Im complaining about my baggage which was not received

Recently, I have traveled from Tampa to Hyderabad on Dec 20 through United/Air India airlines. At the time of check in United people said that I have to collect my luggage in Hyderabad but unfortunately I didn’t receive my baggage. When I went to raise a complaint Air India people said that I had to collect my luggage at bombay and check in again (which was not at all instructed to me earlier). I have lots of stuff inside my check in bags as I’m coming to India after many years. They have raised a complaint “HYDAI70886”, but haven’t received any updates till now. Tried calling and emailing them but no response.
