They put my package on delivery one day, i saw the parcel go to the delivery point through their live tracking but the package was never delivered, my package then disappeared for like one week, they told me to open a dispute because they didn't know the whereabouts of my delivery, eventually after one week of mistery my package was delivered. Really i don't know what to say, improve your info systems!
