Advertised 'special' non-existent

I added an item to my cart that was on special for R36, but once i went to checkout I saw the price had defaulted back to the original R50. I checked this with a few different items that were also supposedly 'discounted' by adding them to my cart and then seeing that they all then defaulted back to the original price. I sent an e-mail to customer service notifying them of the problem and expecting it to be fixed, their response was very unhelpful, at no point did they take responsibility and say that it would be corrected, just that they are working 'to make things more easy and convenient'. They also stated that it meant that the item was no longer available at the advertised price, to which my response was is it not then deceptive to keep advertising the item at a reduced price, drawing people to the site but the special does not actually exist? It is now almost two weeks later and still has not been fixed. The special still appears, including advertising on my Facebook feed. I have always been very happy with Takealot but this has left me a bit worried.
