Delayed Baggage Compensation

I was travelling by Malaysian airline on 27 Nov 2007 to Vietnam for an official visit for 4 days.
It was Mumbai - kaulampur - Vietnam. Hence there was connecting flight from kaulampur - Vietnam. When I reached Vietnam I did not receive my baggage.
Hence I had actually had to purchase clothes & personal belonging. I received the baggage almost 36hrs late. I was told that I would be paid compensation. I haven’t received anything till date. I have written about this to airlines, i even personally visited their Pune office. The only answer I get every time that we will get back to you. Please give me assistance on the same.

Thank you
