Game carnival mall. Your customer service is very bad. Sometimes I would call and not be able to reach him

My sister bought a Defy fridge on the 2nd of February 2022 at Game carnival. In April 2023 the fridge started giving us problems it was not cooling, I went to the game store and they logged a call. Technicians came and fixed the fridge. It was okay for a month or so and it started again. To cut the matter short the technician guys came more than 5 times in my home just to fix the fridge. In November 2023 Defy gave me a new Fridge . After a month the new Fridge I got gave me the same problem as the one they took. I went to Game carnival mall and spoke to the manager name Ishmael told him that I want a refund for the fridge cause the second one is also giving me problems. The respond I got was that Defy is the one who should refund me not them. Mind you I bought the fridge at Game but now that I want my Defy must refund. Since November and now it is February I don't have a fridge. I can't do groceries on things that stays in the fridge. I've lost food that was rotten due to fridge that is not working. Why is so difficult to refund me as customer. The service that I'm getting is very poor. I don't advise people to support Game Carnival mall. Ishmael the Appliance Manager you are falling me.
