Sixty 60 mess up with JC leroux special

I saw on the app a JC leroux special that says buy 2X6 cans for R30. I placed and order for 4X6 cans. When I got the e mail I realized that I have been billed for over R200 as I didn't check the price when I paid. I then called them and asked about this price as I should have paid atleast just over R100 with delivery and tip included. Then told me it is an error on their side and can't give it to me with that price. I then asked them to refund me of which they said it takes 3 to 5 business working days. And they only refund on the wallet. I then told them I need that money to go buy elsewhere as it's black Friday today I cannot wait that lo g for my money. They then deliver the JC's and then retrieved them and as I am typing now am still waiting for their call about this whole mess.
