Defective Items on Takealot

Purchased intex queen airbed item on special, Item was defective as it deflated during the night, which is understandlble as some items can come with factory fault. Takealot send me a mail that item is out of stock and I will not get a replacement. Seems like they put items on sale knowing the outcome and hoping to ***** people over with defective items when asked for a replacement they refund you your credit and you lose out on the sale item.
