Laptop Accessories SA dont deliver

I bought 2 sticks of ram from makro online which Laptop Accessories SA is selling through . The order was confirmed payment made. On the day the ram was meant to be delivered I get a message saying the order is cancelled due to no stock however the product is still clearly shown on the website open for orders and you can continue to add it to your cart and make a purchase. Now I need to wait up to 21 days to get my money back to buy it somewhere else. Really not on especially when this is a work item.
