Defective items sold to kids

I am not happy with the service I received from Game in Cresta Mall, I bought a laptop a week before Black Friday and my laptop had issues within a week they fixed it but had more problems in less than 3 months, what they do they tell you to leave your laptop at the customer service and they don't fix anything they just restart your laptop and call you after 3 days and say they fixed it. The laptop is not yet 6 months old but is giving me difficulties, I am not even using it anymore. Worst customer experience.
