Parle — Human Hair in Biscuits

Dear Ma'am/Sir,
I'm writing this mail with very disappointed and broken heart. From last one decade, it was a beautiful bond with Parle Krackjack Biscuits as it was always in stock of the kitchen ready to eat.
As a regular practice, I purchased a packet of Parle Krackjack Biscuits in last week from a local retailer.
Unfortunately, when today we were at high tea, Parle Krackjack Biscuits served with tea to our guest, we noticed human hair stuck inside biscuit(s). It was really horrible and shocking. I checked manufacturing date, it was 20/11/2022, and expiry is expected on 18/06/2023.
It was really not acceptable from Parle. No one has right to compromise our health.
It would be great if you can investigate this and take strict action against reasonable person. I still believe, it was not usual practice for Parle.
