Game Store Kenilworth is pathetic, dont support this store

My father in law bought a Laptop at Game Kenilworth in Feb 2021, this is the second faulty Lenovo Laptop we bought, after speaking to Lenovo after speaking to the Game call center, Lenovo tried to fix remotely, after 8 months of struggle we took the laptop back to Game Kenilworth and Spoke to Danie Swanepoel (manager) we had to book the laptop, in December, we only got the Laptop back in January only to find ouit Lenovo fixed the wrong component, laptop is even more slow now, and Game wants me to book it in again, after they indicated the incorrect fault on the Laptop. How do we work with no laptop, my father in law uses his laptop for income purposes, and with Covid its dire straights losing out on food for the table. Game couldnt care less, their attitude is "sorry this is Lenovo's fault, not Games" and to top it all off I its now out of warrenty conviniently, We want our money back, as we were more than patient
