The do not honour express overnight deliveries.

I ordered a computer part from a company that utilizes DCB Logistics, which that I needed urgently. I placed the order and paid before 12h00 to ensure same day dispatch, and paid for overnight express delivery. However by the next day at 16h45 I had not received the package. I phoned to inquire about the status, only for them to phone back and say the package would be delivered the next day. Shortly afterwards I received another phone call from them to say that they lost the package. It was scanned into the warehouse, never scanned out when the driver took it, and the driver has no idea what happened to it.

Lesson: If the company uses DCB Logistics, don't order from them, or if an alternative courier is available, rather use them.
