Maggots coming out from hisense fridge

I had bought a hisense fridge from makro about a year ago.... I had placed numerous complaints about the first.... Firstly the fridge was not working, the freezer part of the fridge was constantly defrosting, my meat had gone bad in it, to such an extent that maggots wer in the meat, thereafter after several defrosting, the fridge was stuck from being frozen,,,, technicians came out 3 times and telling us to Defrost the fridge, one technician actually said daily.... I asked them to take the fridge back and they refused, saying that I should open the fridge every 45 minutes.... I am angry as hell... Now asked them to remove the fridge from my property
