Faulty fridge/freezer combo with no assistance from Defy

Seems it is not even necessary to write a complaint if you look at the amount of negative reviews Defy already has. Been struggling with our new fridge/freezer combo from day 1 when we bought it 2 years ago. Every now and then a technician gets sent to do a re-programming as my freezer defrosts on a regular basis (every day, can't stand the smell of defrosted fish anore) and the fridge freezes my fresh goods. The water dispenser has also not been working for the past couple of months. After the technician fixes the problem it occurs again within a day or 2. For the past 2 weeks I have been told my complaint has been escalated to the service manager, but no other progress has been made. Will not recommend this brand to anybody, purely for the terrible (non existant) after sales service
