Bad electronics and bad service

I bought a laptop in July it was a gift for my little sister as she is in matric,I didn't use it within 7days as I was not told and it was not mine I bought it in Klerksdorp.My mother took the laptop back on the 18/09/2017 they did not want to take it instead they said it was a virus,I then came to mafikeng to collect it took it back to Klerksdorp on the 21/09/17 they then said it was a software problem,we sorted everything out but still the laptop was still giving us a problem.on the 31/10/17 my mom took it back again and still they couldn't diagnose the problem I then came to Mafikeng to take it back again for the 4th time,Mr Botsang was the gentleman assisting with the laptop all 3 times then sent me to customer service Sanny Phoko the lady from customer service then told me it's a hard drive problem,I then wrote down her name she was not pleased she instructed me to scratch out her name as she doesn't like people writing her name with attitude.I do not want anything to do with game stores electronics the laptop has not served its purpose instead I have lost a lot of money by installing apps on the laptop,I am not happy extremely disappointed because every time I take a laptop back they tell me about first 7 days so I take it the life span of the laptop was just 7 days.Game stores Mafikeng Mall
