Pureit / Hindustan Unilever — Faulty product

Address:

Chennai, Tamil Nadu, 600039

I got my PureIT on December 22, 2015. Within 7 days, the water started leaking from the back side. Raised a complaint and asked them to replace the product, instead the technician said he will replace the faulty part. After replacing the faulty part, after 15 days again the water started leaking from the back side. We raised a complaint to replace the product because this issue is been happening frequently, but nobody is calling us back. We want the product to be replaced ASAP, or else refund the 17000 which was spent for the product and 850 for the extra part that was bought to install the product.
