Talealot not honoring their pricing on the site

Ordered a book on takealot for R269. After 5 days, I was informed that my order was cancelled due to unavailability of the item. In a day or two the item pops up on my wishlist as available for R373. I contacted takealot to find out why they cancelled my order whilst they had the product and the insisted that the seller "readers warehouse" controls their own prices and they cannot provide the item to me for the purchased price. I am unsure what the technicalities of price changes have to do with me when I purchased this item prior to the prices being changed.
