St Courier — courier missed

I bought a imitation jewelry set from Chennai. I paid RS 600 for jewelry and Rs100 for courier service. The parcel is missing. It's is the mistake of ST courier. They have to bear the loss of parcel and pay amount to me. But they are so irresponsible and not resolving the problem. Worst courier service in resolving complaints. I need full refund of money. ST courier does not aim on customer satisfaction . Never understand the problem of customer.
