Incorrect pricing

So I saw a baby Walker advertised for R60 and I had ordered it. The next day I have received a msg from takealot

Takealot Logo Cancellation Notification Order Number: ***3 Estimated Delivery Date: 2021-06-30 Hi Keshnee

Our supplier has notified us that they no longer have stock of the following item(s) in your order. We've therefore unfortunately had to cancel the item(s) from your order. Today I have logged in to my account I see that the item has increased to 799-99 and there is stock. Just because there was a pricing error they cancelled my order. Customer is king… the price I had seen is what i should get it for.
