I bought from China via courier DPEX.
In South Africa, DPEX passed it on to www.sharplogistics.co.za They charge 3x more than DHL! (50%, DHL is about 18%)
They are sharks and there is nothing that you can do because they have your parcel.
DHL, FedEx, etc delivers in 3-4 days. sharplogistics took 5 weeks!
Then they deliver without notice and complain because I am not ready to received them.
