Non delivery of airfryer

I bought an airfryer online from Makro on 27 February 2026, and the delivery date was given as 4 March 2026. I have been waiting for the delivery up until today, 13 March! I sent two emails but that did not help much. I got a call and was told that my case had been escalated to some higher office and I would be informed of the outcome. Nothing came my way. On 13 March, I phoned and was told that collection of the airfryer from the supplier failed twice. I fail to understand how collection from a supplier fails. Unless of course if the item is out of stock, then obviously the courier has nothing to collect. The delivery of the airfryer was supposed to be in Pretoria. I have asked that the order be cancelled and I get a refund else I may have to wait for an eternity
