R14,000.00 fridge not working properly

I have a double door Samsung Fridge/freezer (Model: RSA1DHMG).<br> <br> After purchases of the product and installation as per manual, the fridge compartment didn't cool properly. Technicians inspected the fridge and found it is not functioning as should. The fridge was replaced with a new unit. Yet struggling with the same issue. Fridge is set to 1 degree. Computer has been reset several times.<br> <br> Thermometer (placed inside fridge) indicates fridge at 8 - 12 degrees. My fridge is not cooling properly. I work late in the evenings and cannot get to Samsung center in time. I have been attempting to call the provided technical support, yet I am always on hold.<br> <br> The fridge is not cooling the content as should. It is an expensive product that is not working.
