FAULTY FRIDGE

I made a purchase of a hisense fridge. 2 weeks later the fridge door has corrosion and the fridge top does not keep cold. I logged a return request and even after a hisense technician came out and confirmed the that the fridge door insulation foam was coming through and that should not be the case and they picked up a issue with the freezer. Makro still decides to decline my return request with no other alternative. It's DISGUSTING! I spent R8000 for something that hardly works. Now I must sit with the problem and nobody contacts me back with a way forward and they have theee dumbest customer service representatives on earth SIES MAKRO. I'm gona be taking this further as we cannot let these so called big company's ****** us
