Spice Jet Airlines — damaged baggage in check in

Address: U-3, Green Park Extension, New Delhi, Delhi, 110016

Hi, this is Neelesh. I travelled from New Delhi to Hong Kong on 11th June, 2019 in Spicejet SG 31. When I received my check in bag at Hong Kong airport, it was in severely damaged condition. The baggage was deliberately cut using some sharp object, as it was almost impossible to do that much damage by mistake. My bag was not locked, when I submitted for check in, so if it was done for some checking purposes( that I think, may be an excuse to be given by Spicejet authorities) then why was it not just opened and checked?!
Why was the suitcase torn like that in such a rash manner? What type of rash services are being provide by your staff?!
My suitcase was a "POLO CLASSIC" model, that I had bought just last year, worth RS 5500.
I also complained about it at the Hong Kong airport and have got a complaint no. with a copy, that I am attaching with this complaint. I am also attaching the images of my torn suitcase, that has made it impossible to use now. Please look into the matter, and do the needful to fulfill the losses incurred by me by either replacing the suitcase with a new one or paying me the equivalent amount.
