Broken Promises and Delayed Refunds: A takealot Disappointment

I ordered a device on Takealot and have been excitedly waiting for delivery, scheduled for tomorrow. Today, I receive an email informing me the order has been cancelled as the supplier no longer has stock. How is that my problem? Takealot took my money - they didn't say "we'll check if our supplier has stock and then charge you". They indicated the item was available and took my money. They consummated the order. They have been sitting on my money for almost two weeks.

To add insult to injury, they tried this: "If you have already paid for your order, we've credited your Takealot.com account and we will automatically apply this credit towards your next purchase." I specifically had to make the effort to go into my account and request a refund that I now have to wait 3-5 business days for. No instant transfer to rectify a mess of their creation.

By accepting my order, they also prejudiced my ability to take advantage of other specials. Now, I am forced to expend more time and effort - and probably more money - to source the product elsewhere.
