Disappointing service

A parcel containing nuts etc was sent from Kzn by supplier on 23 March, a video was made by the Supplier as goods were being packed, in order for me to check it on arrival. It took a week, apparently it was sent back to Kzn, the previous month it was also delayed as it went to Northern cape, only then to Cape Town. The driver who delivers the parcel and has been doing, polite. However, when I videod the parcel being opened by the courier guy driver and checked it against my Invoice for the products which I prepaid in FULL, 2 items were missing. The 2 were at the bottom of the box so box was obviously opened underneath. Numerous pics which supplier took and which I took to compare, including videos were sent to the driver who passed this on to Boss, I have been awaiting phone call since Friday morning. The supplier has also advised that he will not refund /credit me for the missing products, I am bearing the brunt of the loss and having to inform my clients who order from me that I am unable to supply. No doubt, they will not order from me again and this impacts on my small business. The company in Kzn who supplies the products, use The Courier guy on a regular basis. The contact details of the Supplier has also been sent to The Courier Guy. Some form of assistance would be appreciated.
