Defy Fridge that makes loud noise

On 13 March I ordered a fridge from Hifi Corp’s website. On 20 March I logged my first complaint after the fridge began making a persistent, loud noise that made it unbearable to have running near living spaces. I reported this to Defy, the manufacturer, who replaced the unit on 3 June — however, the replacement fridge developed the identical noise fault. Defy then replaced the unit a second time on 13 July, and the same fault recurred again. I am dependent on insulin (Type 1 diabetes), I must keep my insulin refrigerated at all times. Because of the unbearable noise, I have repeatedly had to switch the fridge off, which has caused my insulin to spoil. This has directly affected my blood sugar control and led to my hospitalisation.

I no longer want a further repair or replacement — under Section 56 of the Consumer Protection Act, having had two failed replacement attempts for the same defect, I am entitled to a full refund. Defy has sent a technician to me 3 times who confirms that the fridge has a factory defect and it makes noise that is unbearable but Defy keeps on saying I refused the repair, I dont understand what that means. Ive been patient with Defy since April, I will have to take this to CGSO .
