Pick n Pay - Pnp asap incomplete order received but charged full amount, impossible to get hold of a person in customer service to assist

Incomplete order received. Driver just said it wasn't there. I've been trying relentlessly since my incomplete order was delivered on the 29th of November to get hold of anyone in PnP ASAP Customer service department through various platforms as there was no indication that only half my order would be delivered. Absolutely no correspondence or communication from PnP ASAP as to why or when I can expect my full order to arrive as I paid for the full order.
