Expensive electronics that don't even function

Makro Stubensvally just doesn't care about their customers its actually disgusting, i went there to report an issue with a fridge bough at Makro Strubensvalley I was told a technician would contact me to come and check the fridge, a week later still no one called me, I had to report it on twitter before someone actually came to assist with the issue. Technicians have been to my house 4 times already to keep repairing the ice maker which has been replaced before. We constantly have issues with the ice maker for the fridge, the technician confirmed that the ice maker has a problem once again and would need to be replaced. We are so tired of all these repairs, this fridge is not even 2years old and they want to replace the ice maker for the 3rd time now. We demand our money back for this useless product.
