Deliver broken products then they ignore you

We purchased a Hisense fridge via Game Online stores, it was delivered on 03 October 2022. Three days after being delivered we had to switch it off as it wasn't keeping anything cold. The motor switches on for a few seconds and then off. This happens non-stop and the motor was overheating whilst the fridge was not getting cold at all. We logged this with Game stores on 07 October 2022, who indicated a technician from Hisense would be contacting us. It has been weeks and nobody has contacted us. I've called Game on multiple occasions and nobody is helping. I've sent over 6 emails and have not received a single response. They hang up when you call them, then they phone back and as soon as you answer they hang up again. Surely to make it look as though they tried calling me when truly they did not care to speak to me at all. Since I purchased a brand new fridge and received a broken one, I don't want a technician to work on the fridge. I want a new fridge - which is what I paid for and didn't receive. The customer service is non-existent and shocking to say the least. After this experience I will not be purchasing from Game stores again.
