Takealot.com getting too big for their britches

Ordered and paid for goods on 23 November 2020, according to website tracking shipped on 28 November, left courier facility on 29 November at 01h26. Delivery date 4 December and nothing arrives. I sent a message via their system and called. I get told the purchase hasn't been sent yet and is still at Takealot.com but my concerns will get passed on. The ONE item that I really wanted was apparently "lost in transit", from where to where heaven knows seeing as it never left the facility. I ordered this product when it was stated quite clearly on the website that there was X amount in stock. I have requested a waybill number to track my purchase and have till today still received no information. The total lack of communication regarding the purchase and delivery date is unacceptable.
