Asus India — asus notebook r558u

My laptop is showing boot error and not detecting the hard disk.It is still under warranty and It has been 12 days since I registered my complaint
You say your engineer would visit in 2days but they keep saying me your parts are on the way and as soon as we receive them engineer would see the laptop.
But sorry sir it is difficult to believe anything in India would take 12days to reach somewhere.
It is final year of my college and all my project details are in my laptop and I have to travel to another city for my training but just because of your delay i am stuck at my home and can't make any progress about my work
Sir please you guys should understand the value of customers time and atleast first send your engineer to the location even without parts so he can actually determine the problem instead of just guessing it and making us wait.
