Mr Delivery via Takealot

Delivery notification received early morning 27/11/2015 that parcel will be delivered before 15:00 that afternoon - no delivery received. Made contact with mrD to query, requested that delivery address be changed - issue with that. Delivery office contacted me around 18:00 to advise that parcel will be delivered around 19:00 - nothing received and waited till after 21:30. I phoned mrD again (numerous phone calls between obviously) on 28/11/2015 - agent told me delivery depot will phone me within 30min to arrange delivery at new address (3rd address). Noted a message on the wrong phone number late that evening, since then no contact from mrD. Advised mrD that purchase was urgent for Friday evening as it was a gift, had to purchase alternative from a store which renders my Takealot purchase pointless (not to mention my time spent/wasted and multiple phone call cost). To date no delivery made...why then make use of Takealot?
