Makro Doesn't Want To Help On Their Faulty Products

My parents bought me laptop on the 3rd of April 2018 while I was away, I got back home on the 21st of April, I opened the laptop on that day, everything was working fine up until the laptop made a funny noise and it automatically shut down, it shuts down every approx +-30 minutes of usage, so today, because I had a chance, I took it back to Makro (Crown Mine), they said to me the laptop has passed 14 days so there's no way they can replace or refund me, the best solution is repair, for God's sake, I haven't used that laptop for more than 14 days though, and they saying to me the repair will take 4 to 6 weeks, how am I supposed to do my school work, even the technician couldn't give me the best solution, what is the best solution for this situation? Update: This is my second review since Makro didn't want to solve my problem, I've realised that my laptop shuts down when it's moved.
