Hisense fridge freezer 508l

I bought a Hisense 508l fridge freezer at Makro. When I switched it on, it just ran, and ran, and ran.... Almost all night. It was also making a bad noise, so I switched it off, and requested a return from Makro. After MANY emails, they apparently have referred this matter to Hisense for investigation and assessment. But I have heard NOTHING from anyone. Looking at the reviews on Hellopeter, I am so sorry that I didn't see them before I bought the appliance...I would have gone with a different manufacturer who actually cares for their customers. In the meantime, we are now without a fridge freezer.... Do you understand how much of an inconvenience this is?!?!? Please, please, please help!!!! I am living in hope
