Shocking service, and still no end in sight

Absolutely terrible service from Makro. I ordered a fridge with a 5 day delivery estimate as my tenants were without a fridge. I followed up on the day of delivery to be told there was no fridge in stock in Ottery (there was when I ordered). I followed up again the next day, and the following, and then on my own investigation established that there was stock in Montague Gardens... I'm not sure why it's on me to determine this. I then requested that the order be re-routed through Montague Gardens since they had stock. I re-requested this twice until I called again and was told it was allocated to Amanzimtoti, literally on the other side of the country. I asked the agent why, as it made no sense, and he told me it was correct and the courier would deliver it. This was 3 days ago. I'm now on hold (R100+ airtime down the drain since this started, and still counting). The current agent has told me it must be a mistake that it's in Amanzimtoti, and she wants to re-route it back to Ottery, where I can see online they don't have stock. The levels of incompetence are beyond me.... My tenants have now been without a fridge (during the Corona Virus crisis, just to add salt to the wound) for 2 weeks, and I'm no closer to receiving it... I'm writing this having been on hold for 15 minutes waiting to talk to a manager. Oh and throughout all of this I've called about 7 times... Every single time I've been promised a callback, and I've yet to receive a single one. What are you going to do about this, Makro?
