Expensive for nothing fridge (we want our money back)

LG electronics are a total waste of money, we bought a fridge for over R16000 and the ice maker keeps giving us issues, their technicians have changed the ice maker and guess what? the new one is still giving us issues and they keep sending technicians to come and repair this useless product even though I've reported to Makro multiple times that we do no want the fridge no more because its not functioning as it should, we have had it for less than 2years yet technicians have been to our house 4 times already, this is completely unacceptable for the amount of money we paid.
