Get it wrong every Time!

We have an account at Time Freight, every parcel we send with them is a complete disaster! I cant complain about the service because we get none! Every single consignment we send they either switch the stickers and waybills resulting in the wrong parcels being delivered to the wrong customers, parcels marked clearly sending them to the wrong delivery depots. The last consignment was absolutely the last straw, I delivered a parcel to their depot in Ellisras, the front door was locked, the emergency cellphone numbers on the door rings inside the depot I could see through the window that the roller doors where open, I walked around the back, the depot full of parcels but absolutely no one in sight, I phoned their regional offices in polokwane I am still waiting for feedback. Never the less eventually tracked down a driver and handed in my parcel on the 17/08/2015 consignment to Capetown. Today the 21/08/2015 Capetown branch phones asking for the delivery address IT WAS CLEARLY WRITTEN ON THE BOX and COLLECTION NOTE!!! I have photos to proof my point because all we have had is trouble!!! At the end of the day my parcel will only be delivered the 24/08/2015 is this how they do business?
