Defy faulty fridge

In 2018 I bought a DEFY fridge from Tafelberg Furniture in Paarl. In the first week the fridge was replaced with a new one due to the ice maker not working and water leaking. Since we received the new fridge the ice maker has been replaced approximately 5times. The fridge is still under warranty but when it expires these cost will be for my account which is not fair taking into consideration that we had issues with the fridge since the beginning. I have address this issue with Tafelberg with no success. I would like my money back as I have lost faith in the product (this request was send to Defy directly in 2019 as well).
