Bears expensive price for low quality

My mother bought her 2 door Russel Hobbs fridge last year August April this year the fridge just became warm n didn't function well. I had to lay a complaint in order for bears to fix it eventually in June they fixed it now in September it's warmer than an oven. I don't understand how you sell quite faulty electronics at such an expensive price. We paid cash for this fridge n not even credit. I would like for bears to give us a full refund as clearly this is not the services we paid for!
