Why bother ordering anything from takealot who then, 8 days later cancell because they "don't have stock."

Really takealot, you let me know on the site that the order I placed could only be delivered in 8 days, which was ok as I had enough of the fish food to last until then. Now 2 days before you were due to deliver I receive an email stating, oh, damn, we are cancelling because we don't have the stock. That is simply disgusting. And no I don't want a credit, because how do I know you will not cancell my order again. Just refund my monies.
