Pureit / Hindustan Unilever — Pureit / Hindustan Unilever Faulty circuit board in pureit uv + ro

Gkk2 kit is replaced recently as indicator is pointing to it even it was replaced just few months back. After the gkk2 kit is replaced the indicator started showing the same within 3 days. When complained they have rest the device and the gkk2 showed back to normal. Latter after 2 days only it started again and now they told it is problem with circuit board. Asked the authorized agency So it should be an problem even before with circuit board before gkk2 is replaced.? Complete waste of money for the kit replacement then ?. Now they again asking around 5K to fix circuit board. After reviewing the forum i came to know it is common for many users. Very bad services. They should do the circuit board replacement free of charge as they already wasted my for gkk2 replacement.
