Makro no stock excuse

On 20 Nov I received email from Makro with black Friday special. I ordered JBL 720BT headphone for R200. I received confirmation of the order on 20 Nov. The very next day 21 Nov I received an email saying that they going to refund me because there is no stock. On 21 Nov I went back to the email clicked on it and they do have stock but now at R1299. They realized that they made and error and the best way out for them was to say "no stock", which is not true. Instead of honoring their the mistake they opt-out by saying no stock. I am very disappointed in Makro and the lack honesty they displayed. Beware of Makro specials!!!
