Asus India — diwali offer not yet fulfilled

I had bought asus zenbook worth 77000 on 19 oct 2018 from asus dealer at jaipur. As per the diwali offer, on deposit of additional 999, a seagate hdd could be asked for which i did.
Till date he hdd has not been received. The customer service of asus is pathetic. They just make you roam around in circles as they themselves are not clear. Some one would redirect to redemption team, when you reach redemption they would send you to support team but no one would address and resolve.
The ticket no is adw129716.
