How bad is the service

One doesn't known just how slow the post office service is until you use registered mail! I always thought that registered mail was a sort of priority delivery srrvice , how wrong. Handed in a reg parcel at Knysna to be delivered to Somerset West on 11 Jan 2016 today 30 Jan still hasn't got there that's three weeks to travel 450km!! Sent a second reg letter to Somerset West it got to George 60 km away and for 16 days it has stayed there!!
