Acer - Benq Dlp Projector — LCD projector is not getting serviced even it in warranty period

Basear had purchased LCD Projector around 10 months back, from 1st day itself overall approach of dealer was bad.
In the month of sept projector stopped working, we gave the machine to Raisurana & Sons the authorized partner of ACER in Jamshedpur.
He assured that projectore will be OK within 15 days, now the dealer is asking for Rs.20000/- agains the repair even the machine is in warranty period.
I am amazed with the rude & fraudlent character of the company.
