Pureit / Hindustan Unilever — Faulty circuit board in pure it classic g2 uv + ro

Address:

Shivam society, lunawada road, shahera-389210, Panchmahals Gujarat

I bought pureit classic G2 uv + ro in june 2020 at rs 12000/-.
It has an advanced alert system which will notify filter change after 6000 liter water filtered
In may 2021, i ordered for gkk2 as alerted by pureit system, for rs. 3150/-
Technician from pureit visited and installed gkk2.
After three months in September i found that filter is not working
When i complained to pureit service center technician visited and he said that there is problem with circuit board and it needs to be replaced which costs around rs. 3200/-.

After 1year and 3 months of purchase they forced me to spend almost 3150rs(gkk2) + 3200 (circuit board) = 6350Rs
Why i have to spend this much amount on product worth 12000

Even before completion of 1.5 year, if circuit board needs to be replaced what is the value and quality provided by pureit?

Pureit is even worse than chinese counterfiet products
