SpiceJet — lost baggage

We were traveling from bagdogra to mumbai via banglore by spice jet airline (Pnr pcb56t)
We reach mumbai on 7th november at 01.00 am and one of our bags was missing
Nobody from spice jet staff were available in baggage service office
After a long search and several calls from the information desk employee, 1 spice jet staff got available.
Staff member was adamant and without proper answers or directions
Even a superior authority wasn’t available
We raised complaint (Number 38900)
Till 04.00 the staff was not able to locate the missing bag.
Bottom line is my family and i wasted 3 hours with no reassurance whatsoever.
The worst part is we have to leave for pune and now the rest of the communication will be by calls.
