Game Kolonnade WORST company to expect ANY service when items you bought are broken

Most *********** client service ever! We bought a HP Laptop 4 Nov 23 from Game Kolonnade branch. The laptop immediately overheated severely and we took it to Game to investigate on 3 Dec 23. Inspite of the laptop being only one month old, they insisted on sending it to HP. We got it back on 13Dec 23. My daughter was on holiday at the time and she only turned it on on 26 Dec 23. Needless to say, the laptop was STILL overheating severely and she could not use it. We took to Game Kolonnade again on 28 Dec 23, asking for a refund since my daughter hasn't used the laptop at all - it was overheating from the moment we got it. They said it's a general problem with HP, but STILL refuse to refund me. I have been to Game Kolonnade several times requesting a refund since my daughter needs the laptop for online school. She is doing Matric in 2024 via online school. We are less than a week away from the new school year and we need to load books, programs, and documents before school starts on the 17th of January 2024. HOW DO I GET ANYBODY AT GAME KOLONNADE TO DO THEIR JOBS????? HOW DO I GET ANY HELP??? I did not buy the laptop from HP, I bought it from Game Kolonnade and thus its THEIR responsibility to sort this by giving me a refund so that my daughter can get a different laptop to start her new school year.
