First Flight Courier — Courier contents were missing when delivered

Address:

Pune, Maharashtra

I used First Flight services to deliver my stuff containing "Saree and Medicine (tube for external application)" to Dehradun from Pune. My consignment no is M19222326 and date of delivery was 10/8/ 2011.
When this consignment reached the destination to Dehradun on 12/8/2011, it was recieved open crumpled and the Medicine inside was missing. The worth of the medicine is Rs 2800 appx. they just recieved the cover of the medicine and the tube inside was missing. They asked the courier delivering man about it but he said that due to moisture and mishandling it was tore.
I registered my complaints to First flight services through mails which they never cared to answer. Phone numbers given are never answered and once they did that was of no help. they just gave assurance that will look into the matter but refused to shoulder the responsibility and so never returned back to me. I contacted the Courier person from where I booked this courier also didn't reply me satisfactorily, I want to know now that how can I hang their neck and get the medicine or money back for my content.
I dont want to let go all of them just like that and
