No delivery

On Monday the 15th of January 2016 I sent documents from Vereeniging post office to Bethlehem at 10:02 using Speed Service Couriers ( Counter to door). It is now Thursday yet my documents haven't reached their destination yet they were supposed to the next day (Tuesday). I've been tracking them using their track service and still get the same sms response \on route from Vereeniging post office\"."
