Spice Jet Airlines — baggage delayed and damaged

My Baggage got delayed and damaged PNR -AG6TSR
I travelled from Dallas to Dubai with Emirates and next connecting flight from Dubai to Pune with Spice Jet. This connection is offered by Emirates to me.
When I reached Pune on 4th Feb I got to know that my baggage is delayed because of some reasons.
When I booked PIR with Spicejet in Pune office. they were not ready to accept even the baggage claim. after lot of followup I received my baggage on 4th day.
When I checked baggage it was damaged and my trolley bag was without wheels on it. those where broken.
I filed complaint to Spice Jet customer experience immediately for the compensation for damaged to my trolley bag and also delay of the baggage.
Emirates told me as per International air transport regulations your last connection is Spice jet and they are responsible for accepting claim and process it related to any baggage delay or damage.
Spice is not ready to accept the claim and provide me compensation of (INR15000) which I am claiming for all trouble I have suffered with.
