[Resolved]  Hindustan Unilever Pure It — Auto Switch off when battery is over

Hindustan Unilever is claiming that the Pure It device will auto switch off the filtering function. When it comes to reality the function is not working in the devices they manufacture. My customer ID is [protected], I purchased the device in the month of Feb-09. Last time when the battery was exausted, I ordered a battery, after repeated complaints they changed the battery after 8 days. When I asked that engineer about auto switch off option. He is simply saying that in some devices it will work and in some devices it will not work. But on device they are displaying that the device is featured with auto switch-off option. When they are not able to make the device with auto switch off option, why they will give so much of advertisement and fool the public.
