Recovering order value from a shipping company.

Hi, I booked a delivery / shipping company to transport a tabletop with other things from hyderabad to Delhi. I was charged 2K including 2% for shipping insurance & promised tracked 7 day delivery. They took 13 days, tracking number didn't work. And the table top was scraped. It's unusable. Ignored emails, 20 phone calls later I assume I am within my rights to recovery the cost of my order + shipping charges? That is 10+2K. I documented every thing. They even admit they own me compensation on a phone conversation. Before they ignored subsequent emails and never answered a call. Where do I go from here?
