Poor service from Fedex

We imported a sample Dashcam from S.Korea, leaving the exporter to choose a courier service. It left on the 18/11/15 and arrived in JHB 20/11/15. Unfortunately with no contact numb. After 3 days I chased it, the excuse no contact numb. A simple google of our company name would have done it but I guess they are busy. Fedex said there was duty to pay. After arguing, cameras are zero rated Devin agreed he made a mistake and no duty was payable. He told us once the invoice is paid the item will be sent to us. Two days to get the invoice emailed and that after calling twice chasing it!. The invoice arrives and guess what, with duty payable. Yet another call we have to make, to be told it is a luxury item, told from someone, I am sure did not know what a dashcam was. These are security items, they track vehicles via GPS, record accidents, transport managers can view what the drivers is seeing in real time, they can check on the speed of drivers and record routs with automatic uploads to the cloud on incidents. Luxury items!! These are essential security items for the transport industry! After paying the invoice we finally got it on the 26th 6 days after landing in JHB. Never again Fedex.
