Bad after sales service from Game Kenilworth and Defy

I bought a Defy fridge from Game Kenilworth in Cape Town on 24 March 2020. After a few weeks the fridge started freezing the vegetables in the fridge compartment and ice forms on the back panel. I reported this to Game on 15 June 2020 and have followed up on 19/24/29 June and 2 July. The standard response is that there is a three week backlog and my request for a repair under warranty has been escalated. Still no response. Terrible after sales service.
