Poor service at Game store

We bought a fridge at Centurion store on the 04th of May 2024 and already it's not working and our food is getting spoilt. I have called the store and the warehouse and I am being told to wait for five working days for the technician to come and check the fridge. Is it fair on our side as the customers? The fridge is hardly two months old but already is giving us challenges. Furthermore, we are told that if the technician can't find a problem, it will be taken for inspection which takes more than 21 days. Honestly, that's very wrong as we have paid for the fridge. Please kindly exchange our fridge with a new working one. We can't suffer like we didn't pay
