Professional Couriers — valuable parcel replaced with blank papers

Address:

Bangalore Rural, Karnataka

On 1st of August 2011, i had sent a parcel to my home at Ranchi (Jharkhand) through professional couriers. It had sodexo coupons in it worth 3800 INR. The parcel got replaced in between and what reached destination contained blank papers. The receipt given to me had no tracking number or anything similar. Also the receipt says that they cannot be held responsible for cash but things of value like sodexo coupons ,it doesn't say anything.So they should take responsibility.Please Help.
