Highly disappointed in defy

I bought a defy fridge at furnmart nelspruit and it started giving me problems this year in April and I reported it at the store and a technician was sent to my house and the fridge only worked for a week and started acting up again ,I reported it again and another technician was sent and he advised that he will order a new part and never came back till today...I can't buy groceries because my fridge is not working,I have to buy meat daily ,my kids can't even have cereals anymore. I am really disappointed in how defy has treated me in this whole thing . I will never ever buy any defy appliance or even recommend it to any of my family or friends. I don't even want this fridge anymore, I want it replaced as it cannot be fixed .
