No Delivery

Purchased my Unisa books online on the 08/07/2015, estimated delivery was the 21/07/2015. Contacted the Delivery department on 21/07/2015 to enquire where my books where and spoke to a Mr Jason Britz that confirmed that due to their DC moving my books have been delayed by two days and that I would definitely have the books delivered by today Thursday 23/07/2015. I have still not received my books logged online to see that the estimated delivery dates has been moved to the 31/08/2015. My assignment dates will have come and gone. <br> Contacted the delivery department Charmaine S assisted, very calm and collected consultant has promised 3 of the 4 books to be delivered by next week, as their is a delay in the one book and this is why the delay of the entire order.<br> My problem is why was I not told the real reason on Tuesday when I called in enquiring as to the delay in the delivery of my books, instead I had to hear a very different story. Cannot in future purchase my UNISA study books from Takealot as I need to be able to rely on given delivery dates, it would seem I need to revert back to the old ways and actually visit a store
