Asus India — Asus laptop, diwali offer

Address: 627120

I bought ASUS notebook ASUS A555LA-XX1560D on 29/10/15 through on line store and got it delivered on 09/11/15. I registered for Diwali offer within 7 days. But my offer was rejected due to wrong seriel number entry on registration application. The problem was in invoice bill where the seller printed the seriel number wrong. (one letter changed). I found that mistake and sent mail to [protected]@asusfestival offer mail ID and I enclosed the photo of the sticker on box indicating all details. Still I didnt get any reply from their side and I made telephone complaint too. Nothing has happened so far.
