Dissatisfied customer

I have a complaint. I bought a dish washer on 10 Sep 2017 at Makro Wonderboom. The machine stopped working around Dec last year. I called Defy as the machine was still under warranty on 15 Dec 2018 and was told that a technician will come look at the machine. I waited and waited and had to go to Makro in Jan 2018 so they could call Defy to find out what the delay was and was told that a technician will come through. The technician only came after a week since we went to Makro. Upon his valuation we were told that the motherboard needed to be replaced. Since then I have not received any feed back from Defy to notify me of the update regarding the motherboard. I have spent my time and money following up regarding this machine and I have had it with the waiting game. I am really disappointed with Defy.
