Faulty Airfryer

I bought a Bennet Read Airfryer from Makro on 26/11/2023. I returned it to Makro on July 2024 for repairs as digital display was faulty. After 2 weeks of waiting for the Airfryer to be repaired, it again stopped working on 15 July 2024. I again returned the product hoping for a refund or replacement. I was told it must again go for repairs. Why can't I get a replacement model.
