Poor Customer and after sales Service

I purchased a fridge from Homechoice in November 2022. On the 10th of January I heard a knocking sound from the back of the fridge and logged this with Homechoice on the 10th. I details were verified and issue logged and I received reference number for the call. On the 12th the fridge intermittently started shutting off automatically and I called back to inform them about this, and was informed it is logged. On Friday 13th I called back again as I never heard anything from Homechoice neither DEFY which is the brand. I was informed that it was logged and the agent would be following up with Defy. I took it upon myself to contact DEFY and was informed that they do not have any record of any faults logged with them on my details. I tried calling back and wanted to speak to supervisor adn was informed I would receive a callback. On Monday 16th January I called again and spoke to Nthombizonke, I then requested to speak to Supervisor an Layla came and took my call. She was all apologetic and assured me that between herself and Nthombizonke who is senior agent, they will take it upon themselves to resolve and call me back before 12h00. It is now 15h15 and I have not heard anything from Homechoice! I am sitting with faulty fridge and nobody at Homechoice seems to care. Their sales department is very good and calling weekly to offer products on sale, but afraid their after sales service is Non-Existent. Can I please get a callback from someone senior at Homechoice to resolve my concern and get my fridge sorted!
