Navata Road Transport — parcels not delivering

Hi all,
I got a parcel on my name from navatha. They were denying to deliver the parcel to me due to no company seal. I requested them that i will produce my id proof if required. I don't what's the problem to them. I am receiving all parcels with my id proof only from other services. I am getting problem only with navatha. This is new started station. It will take [protected]@15 days to get stamps from our head office. Can i get an update on this.
