Black Friday ****

How is it that TFG (Sportscene) can offer products on their website on black friday, you make the payment and everything goes through smoothly, and then a day later you get notified that they could not source the item you wanted and they just cancel the order and will refund your money. This is not the first time they have just cancelled an order for an item that was on sale. And when the sale was done, they suddenly had stock available. Not even a type of rain check where you can buy the item for the sale price when they have stock. I wont be surprised when the black friday deals are no more, that they suddenly have stock of the item again.
