KIC Fridge Broke in 2 weeks and still have not been attended in over a week.

I bought a KIC Fridge about 3 weeks ago at the Brooklyn Branch in Pretoria and its been almost 2 weeks now since the fridge hasn't been working. At first the top part of the fridge was not working and i had to throw away food that was supposed to last me two months in two weeks. I called them to ask whether cant i have a another fridge delivered so long that we were waiting for their slow service or i buy another fridge and they will refund me because my food will go bad but they said they would not be able to refund me as a KIC fridge technician was going to come for an assessment, which hasn't come since then. The freezer part also stopped working 3 days ago and now i am throwing away the rest of my food. i escalated to the Brooklyn store manager but he also said he cant do anything about my rotting food or my situation. Now i don't have food and i still don't have a working fridge.
