Misleading adverti*****ts

I ordered a couple of items on Makro's online store. These items were listed as "Online Exclusive"

After purchasing these items and successfully paid for it, Makro sent a mail from their "newsletters" email account stating that the price was an "obvious error" and the order will be cancelled. They also claimed to have rectified the prices according to the mail. This was not done as they just deleted the ads.

I've seen Google ads on the internet directing to these specific ads (now deleted) claiming "Price Drop". I have screenshots of all these.

"Obvious error" is very vague since doing a quick search on the internet for similar products clearly show that these products could fall in that price range. Paying R5 for a new car is an obvious error, but these prices were completely in range compared to similar products.

Makro was misleading in its adverti*****t, and even tried to cover it up by deleting the ads (and not updating the price as stated in the mail) and then even deleted my online purchase records with no refund.

I emailed ********** for clarification on the matter yet received no feedback. I've contacted the call centre and they just kept saying the orders are being processed.
