Trackon Couriers — Delay in delivery/ non- delivery and misbehave

One consignment No. [protected] booked from Ambala and reached destination on[protected] at 11.10 AM, not yet delivered even after 50 hr. (More than 2 days). I talked to Trackon office Kota, just now. He told that it can take up to 7 days to deliver, he talked very rudely and misbehaved. My Location is in the proper Kota City & approx. 7 km from the main Trackon office.
