Asus India — not providing spare parts

Address: K. D. International School, Chabal Bye-pass, 143401

I bought an asus laptop for 1, 50, 000 18 months back. Its screen started malfunctioning and i took the laptop to service centre. They advised screen replacement for 25k and i accepted. However now they have refused to provide spare part and asked me to take the laptop back. It is duty of the company to provide to spare parts for atleast 5 years after product launch. But asus india is refusing the same.
