Best Water Treatment Plant Company Indeed

Very good

Best Water Treatment Plant Service

Worst service .DONT BUY THEIR PRODUCT

Can anyone describe the predicament of a new customer who had to service the New RO Eco from their stable 7 times in 7 months !! Attending to their customers seems to be their last priority!!Now they say that some filter needs changing and it seems I have to pay for it.Seriously , the company needs to re-vamp itslef if they need to survive.I bought this thinking that the products from Zero B are good and stable but alas my experience has been other wise.I am seriously contemplating a Consumer Forum complaint for the menta harasment we are undergoing at home.!!

Very True. The worst quality of service by any water purifier company. They dont understand the importance of water. Very inhuman type of service quality specially in Kolkata.
