FALSE ADVERTISING AND NO STOCK!!!!!!

I had just gone into the market to purchase a fridge earlier this month and came across a ad on Facebook which Makro had a Hisense 514lt Fridge on special for R9999,99 I clicked on the link and it showed no stock anywhere in SA I was not the only one who complained about this on the post which has now been deleted. When going onto the ad it took me to the online website which said this promotion ends 31 March and therefore I did not kick up too much of a fuss besides the 5 emails sent to head Makrocare which i only received a mail back on the 19th of March. Because i only saw the ad virtually and noted the expiry date of the 31st of March i decided to give it sometime for them to get stock. All to find out then now when going onto the same link the price is now R13 999,99 which i think is completely unfair, false advertising and against the CPA. Whether or not the online Marketing Team made a mistake that has got nothing to do with me I should get the fridge and the price advertised. I am now told that the special ended on the 14th of March and when I emailed Makrocare it was the 10th of March and how convenient that I only got a response saying that they will speak to the National buying department on the 15th March.
