Hi-Fi Corporation Sold Me a Defective Fridge

During the Black Friday month (November 2024)I bought online from Hi-Fi Corporation a fridge & airfriyer. The process was smooth and efficient. Within a month or so we discovered that the fridge was not operating well, its freezer door had a defective magnet. We became alarmed when the fridge began emitting odious smell. Scared that it was dangerous we turned it off and contacted Hi-Fi Corporation. They sent a technician whose diagnosis was that the fridge had a factory fault because its gas levels were too low for a fridge that was bought two months before. He told us he would file his report after which we would hear from the supplier. I heard nothing from the supplier. Instead I got an sms that my query has been successfully resolved. I contacted Hi-Fi Corporation national offices again. They told me that they would follow up with the matter with their supplier. Nothing has happened since.
