Flipkart — Warranty of product (Serial no/model no not mentioned in the invoice)

Website:

Flipkart.com

Recently I have purchased a Air conditioner from Flipkart with order ID OD[protected], product was successfully delivered and installation done, after that I have received the invoice, but in the invoice product model no or Serial no was not mentioned, only mentioned “ Air Conditioners
FSN: ACNFU3XZTEYAZZVY HSN/SAC: 84151090”
The actual model no/ Serial no of the product is AR18TV3HMWKNNA/AR18TV3HMWKXNA, so how can I claim the warranty with invoice without product model no / serial no, kindly advise Flipkart to reissue the invoice with product serial no / model no
