PRICE FIXING/MANIPULATION??????

I ordered a fan deal almost a week ago and paid for it. Today I got an email to inform me that due to no stock the order has been cancelled and my account is credited. I have requested a refund. On clicking on the link IN THE CANCELLED ORDER, it took me to the listing which now has a greater price and it actually shows that the fans are IN STOCK!!!! *** - are takealot wanting me to now pay more for the "suddenly" in stock item just so that they do not have to honour the in stock order I placed last week. TOTALLY UNACCEPTABLE!!!!!!!!!!!!
