R300 FOR CANCELATION

I canceled an order by mistake, I intended to change my order but I'm usually to fast with my fingers and I cancelled my food order, imagine, would you intentionally cancel an order that would cost you what you paid for it? I don't think so, it literally happened just after the order was placed and they said it cost me R300 to cancel as the store had already prepaid my order and the driver was there for pick up, it was 2 pizzas, no one ever immediately starts with your order so I was **********, for R300 someone must have enjoyed what I paid for. But next time I will be more careful but that was just daylight *******!
