Spice Jet Airlines — worst ever experience from third class flight and lazy useless employees

I had been harassed by spicejet employees from last more than 8 hrs.
Flight 501, ahmedabad to coimbatore, 11th feb 19 at 5:55 departure, crew member jaykishan collected my hand baggage from me, as there wasn't space in cabin and informed me to collect it from checkin baggage at my destination. But crew member with irresponsibility and carelessly lost my baggage. And no-one is giving proper response from coimbatore spicejet office.
This is ridiculous.
Kindly find my baggage and deliver it to me as soon as possible.
