Terrible and frustrating experience with Aramex

Quite possibly the worst service I've ever received from a courier/shipping company. Had an urgent part needed to be shipped from Cape Town to Belgium. Was promised 4 to 7 days. Eventually arrived in Belgium 10 days later and then they proceeded to loose the parcel. Was told an investigation into the lost parcel would take up to 21 days. Would give negative stars if I could. Will never use again.
