Consumer Redressal

Hello, On June 29 2013, I flew with Spicejet flight SG45 from Delhi to Kathmandu. I checked in my baggage, and was given a baggage tag as well. But when I arrived in Kathmandu, my baggage was missing. I filled a complaint form (Property Irregularity Report), and was told that they would try to trace the baggage and deliver back to me. Today, it has been 9 days already, and I have not heard from Spicejet. I have been calling the ground staffs in Spicejet Kathmandu branch, and emailing the Spicejet Customer Service Delhi. However, none seem to be enthusiast about finding my baggage. I have a Dolpo trekking expedition planned for mid-August, for 2 months. And I had all my camping, trekking gears and expensive camera gears in the baggage. I also paid for the extra 5 kilograms for checked baggage. Clearly, the value of my gears are far greater than what Spicejet compensates according to their policy. I am willing to take legal action against them. Please help me. Amit
