Bad experience with Makro Centurion and Defy SA

In May 2022, I bought a non-frost Defy Fridge from Makro Centurion. In August the fridge started giving me problems. The top part was full of ice and the bottom part was not working food was getting rotten. I contacted the call centre for Makro and they logged it in for repairs with Defy. The fridge was repaired but then after one week same problem returned,. I repeated the same process and the technician came after two weeks and repaired, after two weeks the problem was back again. It takes two weeks to report and finally have a technician come home and all this time we do not have a fridge. for the third time the technician came and he said the fridge needed spares, i then told him that I was not going to wait for that, a fridge less than 6months needing spares, can I just have my money back. I was referred to a defy Manager named Thato, who had received the report from the technician, I sent him an email and told him that I needed my money back, he aske me to sent him the invoice, I did, then after two days I decided to follow up on email then it told me that my email address was blocked. May you please help me get my money back, they can come and get their fridge its not helping e in any way.
