Desperately need help for goods damaged in transit by The Gourier Vaal branch

Good day, I desparately need help resolving a product return through The Courier Guy Vaal to Makro.

Background:

The tables had to be wrapped prior to collection. I arranged telephonically twice with the manager/ courier guy contact to collect the tables after 12pm on the 16th April. I have the contact information of the individual who confirmed that they will collect after they are wrapped as they cannot collect tables that are not packaged. They were then collect prior to this UNWRAPPED - The Courier Guy collected them knowing they were not wrapped. When I asked the gentleman at The Courier Guy he suddenly forgot about the arrangement and who I confirmed this with (being him.) Makro wont refund me now and the tables are badly damaged! How do we rectify this? Please please help. I have all the documents from Makro and emails confirming the event to the Courier Guy and whatsapp chats with the respective manager.
