[Resolved]  Aquaguard Total Infiniti — Poor quality and response

I ordered for RO through call ctr on 16th Dec 2009. A service person came same day afternoon and installed the model INFINITY saying there's no need of RO in my place though i've been using RO of another brand named dolphin until then. after two days water from INFINITY started producing white circle shapped stains in vessels and water tasted quite awful. i made a complaint on 4th January 2010 to the call ctr asking to replace the model with what i've requesterd earlier. they said service person will be there in two days. i stopped using the purifier and started buying 20 lts water from nearby supermarket. I waited for a week and called again, same reply.the purifier started leaking and i dont know what to do in this condition. my complaint id is 8237 2615. i made a call again and they said someone will be there by that day evening. no respose so far.
