Cancelled item is in stock.

I placed an order with Takealot on the 27th of April 2016 at 19:59 order #*** which consisted of 8 items one of which was a book titled Magic Tree House 16: Olympic Challenge! For R29 on sale waiting time for the book 7-10 days once received from supplier. Estimated date of delivery 13th May, On Friday the 6th May I get an email from a customer agent Nawaal Salle from Takealot informing me that they cancelled the Magic Tree House book I ordered because their suppliers are "out of stock". So I went online on Takealot to check my order and found that the book I ordered that was cancelled was still available to buy online just at R96. I phoned to find out why they cancelled the book I ordered when it was still clearly available to buy from Takealot, the customer agent I spoke to gave so some hogwash story of how it has not been updated online yet but there is no stock and they can't get it from suppliers and that I would wait a long time to receive my order in order to wait for supplier to have stock, which was a lie because their supplier of that book Readers Warehouse had stock of the item, secondly isn't it my decision if I am willing to wait for an item to become available in stock before cancelling items and sending my order???? I again went on Takealot today 7th of May and have found this book is still available to purchase from Takealot at the lowered price from R96 to R48 and it is "in stock" at their Cape Town warehouse. So please tell me how is it possible for Takealot to cancel an item I wanted without consulting me? an item which has still not been removed or updated on their online website as "out of stock" but instead altered from the price of R96 to R48 and changed from a waiting time of 7-10 days "to in stock in Cape Town". This is unprofessional business practise and I don't accept hogwash nonsense as an excuse to not supply me with the book I ordered.
