Asus India — Worst laptop

I bought my Asus laptop notebook X505ZA in october2019. I'm having the worst experience with Asus. I trusted the brand name but it is not worth that's all I can say. as the warranty period is completed it started working slow day by day.i went to asus service center they said the keyboard has crashed(due to moisture) and motherboard is not working (the ASUS motherboard is very sensitive?...it got problem even when i didn't used the laptop much) they give me estimate of 30, 300 rupees and i bought this laptop for 30, 000 from paytm mall. Is this justified? they are making customers fool..?? right?? they sold the defective item on e-commerce site (paytm).and i was the unfortunate customer who trusted on Asus. After that i contacted many people around me who are using Asus. They are also facing trouble with their laptops. In the past 1 year and 11 months the laptop was only used for 50 hours maximum and this happened.It is the time to correct their fault. I'm very upset with all this. My laptop has very important research data. Please don't make me think that I wasted my money by trusting Asus.

Kindly look in to this.
