Asus India — asus service center is denying warranty on my product

Address:

Bhagalpur, Bihar, 813203

I bought asus apwu001 mobile charger from flipkart on mar 23rd 2019. The description as well as package was clearly mentioning 6months warranty. So few days ago it stopped working. As it was having 5 months warranty remaining. I went to asus service center bhagalpur to claim warranty. Where they denied warranty on my product. They told me that they don't give warranty on asus accesories bought from flipkart. I have even registered product on asus website. 5 months warranty is remainig. They dont even checked or examined charger.. They just told me that they won't see it because i have bought it from flipkart. Even though the asus official website on clicking on where to buy opens that flipkart page. Here's the link https://www.asus.com/in/Phone-Accessories/ASUS-10W-Adapter-Micro-USB-Cable/
I have been trying to contact asus aswell as flipkart but no responce.

Replace my adaptor as it's still in warranty and there is no physical damage. Asus service center can't just simply denied warranty without even seeing it. They are scamming by not giving any services on product after selling it even if it is under warranty period.
Here are the details

Product name - asus 10w adapter micro-usb cable

S/n - k2acgks00188

I m adding invoice and other pics
