Takelot cancelling orders with excuses

Both myself and a friend has ordered a baby walker on Takealot.com. The price was very cheap (maybe priced incorrectly), so we bought the item. The next day we received emails saying that our orders are cancelled. This is unacceptable to me. If any other store priced their items incorrectly, they would honour the advertised price. When I emailed them, they simply said the item was out of stock. When I told them I would accept a similar item, or wait until they have stock, but still pay the cheaper price, they said that the product had been recalled from their side. It is obvious to me that they made an error in pricing, and now they are making up excuses
