Takealot just keeps rescheduling deliveries with no products

Courier service was atrocious (Fast and Furious delivery) only wanting to deliver 2 of my 11 items and force me to sign for order completion. Rescheduled 4 times now and I still don't have my items. Customer care at first responded with generic copy and paste answers. Now, no one is answering my messages and their lines are down. I would like my money refunded as clearly you cannot deliver the products you clearly indicated were in stock.
