Takealot not admitting to their mistake.

I bought a rechargeable fan from the Takealot website. The fan that I received was totally different (and looked very much inferior) from the picture of the fan on the website. I was never notified that the fan supp**** was not what was shown on their website. I then logged this on the help page of the Takealot website. Long story short, after 8 emails (going backwards and forwards) explaining my issue, I was told that that particular fan was out of stock?! It did not show as OUT OF STOCK when I bought the fan. According to Takealot, between the time that I placed the order and delivery, the fan went out of stock!! This I don't understand. There are two other fans (costing more) that show the same picture as the fan that I originally wanted, but Takealot still maintains that my fan is out of stock, and therefore they cannot investigate my issue any further. Takealot have at no stage admitted being at fault nor tried to find a solution for the customer even though this is their mistake. Up till now, I have been a happy Takealot customer, but this whole issue has left me a very dissatisfied customer. This leads me to believe that the customer is not always guaranteed of the item that they order, to be the correct item that they will receive, as the pictures of the item on the website could and might well be incorrect.
