Asus India — Scam lies

I have bought a laptop from asus india and within warranty time its keyboard stopped working so i contacted asus authorized service center they installed new keyboard on my laptop and now again after 4 months, keyboard stopped working, i don't know if the are giving original parts to me or not, and main thing is i use my laptop twice or thrice a week, i don't even play games on my laptop, i use it to surf internet but still keyboard stopped working after replacing with new.
