Trackon Couriers — Courier delivery process

We sent some dry items (medicines) from Kolhapur to Rourkela through Trackon. We paid heavy price for the shipping compared to other vendors. The package is still not reached the destination. Above all, the Trackon people are not available to answer the calls. Someone answered call after multiple attempts and was very ignorant and abusive.
This is utter disgraceful service.

My family member who is a patient waiting for the medicine and these people have no idea where the package is. They have no tracking update since last 7 days.

This is causing a lot of damage to us emotionally and on health. Please suggest we want to file a FIR against this fake courier company.
