Terrible service

I bought a Defy fridge(Sales order-***) at Game cresta on 21 July 2022 and it was delivered on 22 July 2022. The fridge part( Compartment) is not getting cold no matter how much I regulate the temperature. The fridge part is at room temperature and my food got spoiled. I emailed the store Game cresta the proof of purchase with the sale order, also sent pictures of the fridge model number on 27 July 2022 hoping they'd be promt on their reply to exchange the fridge, instead a call was logged for me at Defy appliances on the 28 July 2022. No technician had come to replace, exchange or fix the fridge.
