Very Unpleasant - Be careful of "Special" ****

I placed an order on Takealot for a pair of Ray Ban Aviator Sunglasses which was advertised at R 2,599. Payment was made, Order was place and confirmed, they then postponed my Estimated Delivery Date by a week and then Cancelled my order with the reason "No Stock". However, the same pair of Aviators are now advertised at R3,489 with no record of stock running out. I received my money back, but the principle of advertising a sale, taking my order, receiving payment and then cancelling it because this week the they are charging more is totally unacceptable. Amazing how the price went up by over R1000 just before Black Friday
