POOR SERVICE

I really don't know what to do or say about DHL and their poor service cause every time when I use them there's always going to be a problem. when my supplier who uses FedEx sends me my cargo it always arrives on time without any complications but with DHL I always have to complain first before they deliver as if they're doing me a favour when I'm paying them for their service. <br> I need my cargo tomorrow before I fly to Cape town in the evening cause this is really becoming irritating especially since I'm paying them prior to delivery this is really unacceptable.
