Asus India — Asus Company Not Extended Warranty even after payment done

Hi,
My name is amit kumar. I made transaction of 2499 Rs. for my asus x13 laptop to extend warranty by three years and received the confirmation mail from asus on 13th june 2022 to wait for next 45 days to receive warranty card.
More than two months (60+) days has passed (as on 22 aug 2022), but no mail, whatsapp communication I received from them (not even on mail). Tried finding customer number, all in vain.
Please help me in getting my warranty extended for 3 years as promised. I am attaching confirmation mail.
