Defy poor quality Fridge and bad service on Guarantee and Warranty

It has been less than seven months, yet we have experienced repeated faults. First the compressor failed, then the thermostat, and now the fridge is freezing instead of cooling. Despite these ongoing issues, Defy has declined to replace the unit. This is unacceptable, especially as the fridge is still brand new and less than a year. We are left without a working fridge for over a month, which has caused significant inconvenience and additional food costs. We trusted Defy and Game to provide a reliable product and service, but the repeated breakdowns and refusal to replace the fridge have left us deeply dissatisfied with the brand Defy and Game store products. Kindly review this matter urgently and provide a clear resolution, as we cannot continue with these ongoing failures.
