Spice Jet Airlines — reporting of baggage damage caused by airline workers

My baggage is damaged due to the negligence of the spicejet workers. My suitcase rest case broke badly, complaining about which the attendants response was too had. They were not ready to lodge my complaint, after several arguments they wrote it in a paper. I want spice jet to look into the matter asap and compesate me for the same. Complaint number - 46813
I've attached photographs as proof. The repurcation of the attendees of Spicejet in silchar airport after we reported our concern was pathetic, they were not at all ready to co-operate with us. It is really saddening that the customers are treated this way that too when the fault is from their end.
My fair expectation and demand is that Spicejet replaces the suitcase with a new model or compensate the bill amount so that I can go and purchase a new one.

Flight number - SG3219 (CCU-IXS)
PNR Number - V7UGWS
Kindly do the needful.
