Poor service on damaged goods by THE COURIER GUY

Booked and paid for a business signage to be delivered in the Western Cape The Courier company collected the sign and was happy to accept the signage as I have packed it. Halfway to the destination one of the depots phoned to say that the signage was broken in half. Complaint was registered only to be told that I haven't packed the parcel to standard and that they are not responsible, for the damage and will not pay for the damage. On reply to my question "that one of their personal accepted the parcel as is and should have informed me to secure the package better". The lady told me that their staff are not trained to make that judgement. My complaint is that they should not have accepted the package, and if they DO SURELY, THEY MUST ACCEPT RESPONSIBILITY. R5500 down the drain now
