Adidas is doing wrong selling

I ordered sneakers online on sale for R39 and R60 delivery... Order was confirmed.. Now adidas canceled the order saying the sneaker is out of stock but what surprises me is that the order went through and it was confirmed and now they are coming up with stories... I want my sneakers not stories...that is not how consumer protection act states... Also they are saying that the sneaker is now available but they changed the price... Please send me my order via courier as per request
