Poor delivery experience by Amazon South Africa

Poor delivery experience- courier guy acting for Amazon indicated delivery on Saturday afternoon. Never arrived despite my wife waiting at home all day Shown as delivered by Amazon When queried today Monday was told by the agent that could only provide a voucher or refund for the item When I indicated that I wanted the item and to please investigate was told it would take 48 to 72 hours for the transport team to investigate! Clearly better to use Takealot which is a lot more reliable!
