Hisense poor customer service

I bought a fridge in August 21. Its started defrosting and making noise in October I reported at Makro where I bought. I was then referred to Hisense South Africa. Hisense sent a technicians who could not tell me what was wrong. I made a follow up the next. I was told that the fridge is going to be repaired. Now... How do you repair a fridge that is 2 months old. I did not buy 2nd hand fridge its brand new. Hisense will either give me new fridge or a refund.

My monthly grocery is off. I don’t know who should be responsible for that.
