Order not delivered - no customer service

Ordered a TV online on 22 May 2022. I was told it takes 7 working days for delivery. The 7 working days has long passed. I have been trying for days now to get an answer from them but to no avail. I have emailed, live chatted and even tried calling the Gateway Branch. Nobody seems to know what is going on or where my order is. They have given me a tracking number but the courier company (Dawnwing) says that they cannot trace the parcel. Game should not claim that they can deliver within 7 working days if they are unable to do so. Terrible customer service.
