[Resolved]  Asus India — warranty not approved (case number[protected]

I had purchased a laptop (Make asus) on amazon on december 30th, 2018. At the time of purchase it was mentioned as the warranty of one year on amazon website.
Laptop was in good condition but i faced some issues with keyboard since last 21 days,
So i called customer care of asus india on 4th of september 2018 and discussed about the issue. Their representative told me that they will arrange onsite service within next 48 hours. But on 6th september 2018, the asus india representative told me that the product is out of warranty. And to get the warranty approval send the invoice on the email i'd provided by him. So i had sent the invoice on same day. But i have not got any response till date.
