Consumer Redressal

I shifted my household luggage from Gurgaon to Mumbai on 22nd October, 2013 and received the goods on 9th November, 2013 using Agarwal Movers and Packers (Delhi-based).As the goods were being unloaded, one item no. 10, Split AC compressor was missing. After repeated attempts to local Mumbai office to claim the insurance, they keep saying that they are still finding. It my hard earned money and they are not bothered even to respond. It has been more than two months and to adding to the misery, in spite of repeated follow-ups the response from claims department was very indifferent, casual and as usual lacking accountability. Kindly help in filing claim against them.
