Pathetic service from Defy & Makro Centurion

I bought a Defy double door fridge from Makro Centurion In 2017. I went for holiday in december 2018 only to find out the freezer stopped working and food were spoiled. I contacted Makro who in turn logged a call with Defy to send out a Technician. I was told it will take 48hrs turnaround time. I called this morning and they assured me that technician is on the way..when i called again after 14h00 to follow up, i was told that technician will only come tomorrow or friday...i am now frustrated as all my groceries for January are all spoiled. I Made few calls to Makro who keeps on referring the matter to Defy. I am now so disappointed by a well known brand like defy...i will never buy any appliances with defy name
