Treating customers unfairly

I would like to express my disappointment with Takealot. on the 27 November I did a purchase for karcher k.2360 pressure washer @1499.00 on Cyber Monday which the product was at a discount. The product was on stock and my purchase went through successfully. I have since been awaiting for delivery and to my surprise when I was tracing the delivery, I discovered that they have cancelled the order without any notification or reasons. I'm really disappointed as I was looking forward to receive the product. The product price now when higher almost times two the price I bought it when it was on discount. Takealot please treat your customers fairly and I need the product at the price that I bought with when it was on discount. I regard this as false advertising what you did to me and I hope you not treating all your customers the same. Order number ***.
