Pureit / Hindustan Unilever — posted in twitter no response for my compliant

Address:

Chennai, Tamil Nadu

I have bought pureit water purifier from pureit. From day one facing the issue, with the help of srinivasan it was replaced to new machine. Three months before, i have changed membrane by spending 2550 rupees. Now, technicians say again membrane got damaged asking for 1500 rupees. I/m not ready to pay single rupees, please take necessary action to resolve my complaint.

I've tweeted to higher person in pureit team, no response from them.
