Makro doesn't want to refund faulty fridge

I bought a fridge on the 27th of November 2020. From the first day it started icing up at the back of the fridge. I sent Makro head office email on which they requested more information. Now nearly 2 weeks later I still haven't heard anything back from them. Thursday 21 January I decided to take the fridge back to Makro Polokwane. After loading off the fridge and taking it to Returns, they tell me they're not taking back the fridge as a technician has to come to our house and look what is wrong. Up till now I have not heard anything from any technician. I also do not want the fridge repaired as it is brand new. I want it replaced. Bad service!!
