My consignment with way bill no. [protected] is not delivered about to deliver 15th june 2018 (Picked up on 12th jun'18). I searched company website for posting complaint, but no option available, hence posting here & also they are not picking up their landline no. At aurangabad office so that i can talk with them & take no. Of courier boy for further communication & delivery. I accept here that in my delivery address, there was a wrong pin code mentioned, but of same city aurangabad.
