Inspiron Battery

Hi, I am from Bangalore. I would like to make a complaint with regards to price of a battery for N4010 sold across your online partner and dell exclusive stores. is there any mail id that i can get? Online partner Compuindia says Rs.1890 with 3 months warranty, Dell exclusive store on Koramangala says Rs.4500 with 1 year warranty, Dell sales says Rs.2200 with 1 year warranty and Dell reseller says Rs.2500 with 1 year warranty. Dell Exclusive shop says compuindia dont see genuine products. What is happening guys? is this how you sell your products? Tried calling helpdesk for E-mail contacts to post a complaint but no one is ready share any contact details.
