Pureit / Hindustan Unilever — Insect found in water tank

Address:

Lucknow, Uttar Pradesh, 226028

Hello
I have a pureit marvella ro at my home. A few days ago i got my gkk1 changed as it was blinking red.
2, 3 days ago the water from the purifier started stinking. It was a foul smell. I avoided it thinking of null possibilities of contamination due to my trust on pureit.
Today in the morning the water flow decreased from the tap, but the machine showed tank full indication. I registered complaint and technician came and found almost 5 inches long worm like creature (Centipede or something) stuck in the tap.
1. I want to ask hul pureit (Who claim to clean i crore virus in a litre) howcome such a big thing enter your delicate and advance cleaning system and reach till the outlet tap?
2. I have a new born at home, how can we ensure safety after such an incident?
3. Is some cleaning actually happening inside or there are just some small and big boxes placed to befool the consumer?

I and my family are really afraid after this. The creature almost resembled a small snake. Just imagine, we have been drinking that water for last few days.

What can hul do for my assurance now?

Regards
A very dissapointed customer.
