Kent R O Water Purifier — Water not Purifying correctly

Dear Sir,
We purchased Kent R O water purifier 3 years back in Mumbai and it was working fine in Mumbai however now we have shifted to Jaipur and people from R O department came and said that the R O will not work in Jaipur. Then we called up the local technitican and he fixed some wires here and there and connected it. But we are not satisified with that.

We need someone from Kent R. O to come and check it for us.
Our address is:
Manish Tekwani
201, Akshat elegance.
Bihari Marg, Bani Park- 302016.

Thanks and Regards;

Pinky
