Amazon South Africa No Delivery, no way to reach them

Amazon South Africa’s service is utterly disappointing. My order has not been delivered, despite selecting the correct pick-up point. The delivery company Amazon used failed to deliver, as the pick-up point no longer accepts Amazon deliveries, although this was available when choosing the pick up point online. This is completely unacceptable and shows a lack of coordination on Amazon’s part. Their online chat was useless and provided no real assistance. I was told to sort it, which is their job, as they need to change the delivery details as Amazon is the sender. There is no contact number available to resolve this issue. Amazon has failed to communicate or offer any resolution. I demand a full refund for this order due to their *********** and misleading delivery services.
