Lenovo — Laptop lcd manufacturing defect

Address:	Bhopal, Madhya Pradesh, 462039

I purchased lenovo laptop g g50-80 80e502q61h, s/n pf0cwakb invoice dated 2nd may 2016 through flipkart.in march during normal use, the lcd display started showing black lines in one portion of screen.
I complained to lenovo customer care regarding the same on 18th march, 2017 with all details. Complain number [protected]
Upon this, lenovo staff informed me that there is a damage to the screen and asked me to replace the part at my own expense.
I asked them to inspect the laptop to assure themselves that there is absolutely no damage from my end and the screen has developed a manufacturing defect.
Lenovo staff finally did not agree and behaved adamantly neither agreeing to inspect the laptop nor taking corrective action.
