Flipkart — Invoice not showing product details for my order

Address:

A807, Aromatic Wind, Bhumkar Bridge, Shankar Kalat Nagar, Wakad Pune Maharashtra

I purchased washing machine with order "OD[protected]" in Feb-2022 and
Recently, I noticed a problem. As the device is under warranty I contacted the product customer care and they informed me to submit the invoice.

I have downloaded the invoice from flipkart but invoice doesnt has product information. I connected to customer service but still issue didnt solve.
They are also misguiding by marking issue as resolved on their portal.
