Livpure — Livpure water purifier-leakage problem

Hi,
I am using livpure water purifier since last three years. I have taken AMC plan last year. Since this servicing there is continuous leakage in water purifier. Sai enterprises was the third party company which has done servicing. After leakage they have worked twice on water purifier but problem of leakage was not solved yet. There is no response from customer care. Problem is not solved.
