I have purchased acer laptop e5 573 (Serial number - unmvhsi030g0976848) on date 8th april 2016. After purchasing i am facing two issue within 3 to 4 months, one was software related and another is hardware related. Main issue was keyboard issue. If we purchased any brand product and within 3 to 4 months if we facing any hardware issue so it's not good think. I have raised it ticket in month of aug'16 related to keyboard is fully dead.
O my question is, within 3 to 4 months why i'm facing keyboard issue? It means product is not good or quality is not good and what? As you said, every electronics has no guarantee so i understand but it's not means you selling any product and customer facing these issue within 3 to 4 months if i am spending near by 27, 000 amount on your product so you should provide quality product and again you said to me, if we replaced new laptop but what guarantee of that laptop again are you not facing another issue? It means or i can say it, you don't have trust on your product or what? Because when i purchased your brand product that time i have trust on your product but now i don't have. And if you have not trust on your product then why are you saying to me take your laptop. Just give my money.
Hardly, i had used laptop 3 months after that laptop is in your service center.
