Trackon Couriers — incomplete courier received

Address:

803101

I have recieved incomplete courier material from Trackon Couriers. My Docket no-[protected] has 2 packet out of which only one packet is delivered to us Dated on[protected].
After regular followup (at least 20-25 calls on both mobile no) I could not get satisfactory response from the local Trackon service provider.
Their first response was no such docket no exist and there is no courier to the mentioned address.

Even I tried to contact the Patna Central Branch for more than 20 times, but there was no response from their end.
