Bad Experience With Game - Greenstone

I bought a Defy fridge from Game in Greenstone Mall on 20/02/2021. The day I decided to switch on the Fridge, 04/03/2021, it was not cooling food. I called Game on Saturday, 06/03/2021. A call was logged with Defy. Patrick, a Technician from Defy, called me on Wednesday, 10/03/2021 to schedule an appointment. I told him I only get home at 18:00 on weekdays. He told me he can't come at 18:00 as he knocks off at 16:00 and that I should rather return the fridge to Game. I found his response rather appalling. I don't owe Game any money and their Technician wants to assess the fridge at a time convenient to him? I had already bought food and placed it in the fridge and had hope that the fridge will eventually start cooling. My food ended up getting spoiled. I'm still stuck with a fridge that's not working. At who's expense should the fridge be returned to Game?
