BAD DEFY CUSTOMER CARE

I bought a Defy double door fridge freezer 2020-03-16 at Game in Kimberley. On 2023-03-10 the freezer side stoped working and all my frozen food got spoiled and had to be destroyed. I reported it to Defy. Defy send someone to fix the freezer. A part had to be put in. On 2023-12-22 the appliance broke down again. All my frozen food went bad once again. I reported it to Defy after a few days someone was sent to check out the problem. But during the delay between the fault report and Defy sending someone to check out the fault the appliance began working again (about 3 - 4 days) So when the person came out the applance was working again. On 2024-04-24 the freezer part stopnworking again for the 3rd time. All my frozen food went bad once again. I report the fault once again to Defy. After reporting the fault a person with the name Andre of Defy phoned me, he was very rude and told me that if the appliance start working on its own it not faulty. I told him that my food get spoiled every time and this is now.getting to be a problem because a person must be able to trust a appliance. On 2034-05-03 someone came to check to see wat the fault was. Once again after 9 days the freezer began working again. The appliance is getting very hot. The person Defy send out told me that they had to replace the sensor and a thermo fuse, bit it must be ordered. Today is 2024-05-09, 5 days later. No one came to replace the part. After many calls I cannot get hold of this Andre person. What am I to do. Al my appliances in my house are Defy. I will never buy a Defy again after this. I atleast thought that Defy will replace the frige, because it broke doen 3 times and are still ander warranty.
