Hi,
My friend couriered a parcel of 3kgs from delhi with n20745129 number. No awb no was there on the slip. Took 7850 rs and says that i tried calling on the no given by my sister and got a revert that its not my parcel whereas that number is out of service since a year that means he lied. Then i told him get my parcel i will get it done from the head office coz i cant track it so he tells no its seized from the delhi airport custom and i need 4-5 thousand more to release it. How can we relay on them and i am fedup. Pls help me to track my parcel.
