POOR SERVICE, NO COMMUNICATION

I bought a HiSense fridge freezer combo from Makro Nelspruit around 12 months ago with a three year warranty. On Thursday 23rd August the fridge and freezer started giving problems. Top half of fridge not working bottom half freezing, same on freezer side. On Friday morning I drove to Makro and reported it to the salesman I bought the unit from. He pulled a copy of the invoice and reported the fault to HiSense. As I have no other fridge I requested that this be sorted ASAP. By Saturday I had heard nothing from Makro, and reported the problem on their "Facebook Messenger" page. I got a response and customer care from the store called. They promised to get back to me first thing Monday morning. It is now 14h00 and I have still had NO communication from Makro and we still sit without a fridge.
