Fasle advertising

There was a product on sale at takealot website,it was a laptop and the price was R186 a laptop so we placed an order and we received instant confirmation that the order was placed and delivery will be done before the 16th of August 2021. But 4 hours after everything was confirmed takealot then sent out a cancelation notification saying that they don't have stock, and the product has been removed off the site. So if there is no stock why would they removed it out of the site but other products that are out of stock says out of stock and still remain there. This is very poor service and if no action is taken and we don't get what we placed an order for I am going to take this to social media and post all of the screenshots we have showing this item was advertised and I will not be buying anything from takealot going forward ??
