i don't wanna give a single star to them they are providing poor services. nut without star i cant be able to post this. they got my parcel on 4th April and last week i called them for the parcel and they mentioned my wrong address then i confirmed address. yesterday i tracked my parcel and that is delivered somewhere else instead of my address. how they can do this to anyone's parcel. if they didn't find any address they can call customer or ask them to pickup. but they delivered my parcel to the wrong person's hand and i don't know where is my parcel now??????????
