DEFY products fail and Defy do not fix, Call centre agent Rude

We bought a defy fridge a year ago. The fridge just stopped cooling down. We called Defy on the 4th August 2021. Over a week ago to log a complaint with the Ref ***. To date (12 August 2021), we have been given the round around. I asked to speak to the manager 10 August 2021 and was told the manager will call me back. This was 2 days ago. I am still waiting. I have written to the head of Customer Service and still I am hearing radio silence. I called yesterday (11 August 2021), they said a technician was on his way and was booked out for yesterday. No one came. All the food in my fridge has subsequently gone rotten. Who is going to pay for that. Defy do not care, the product stopped working within a year, the after sales service is shocking and none of its employees care about customer service. The call centre agent actually made me feel like I was an infringement on her day. She was rude and made me feel like I was ruining her day and like she had far better things to do with her time than do her job and provide customer service.
