HP India — Received a damaged product

I've initially received a damaged product and after complaining a lot of time no help from tech team was received instead they denied the request for onsite tech visit. The product was on 14 days of replacement window and registering for the resolution of the issue the tech team failed to send a technician and after the system screen got damaged they are saying no replacement will be entertained as the screen damage is induced that too they analyse this on basis of a video and didn't send the technician.
