Pure IT Water Purifiers — Germ kit got finished in 20 days o[censored]se

I purchased Advanced Pureit 23 L from snapdeal and it was delivered on 24th Aug 2015, customer Id [protected]. We started using it from 1st Oct. 2015 and to our surprise the germkit ended in 20 days. I complaint on 23rd Oct 2015, the technician visited 2 times. I also emailed no of times. Firstly I was told that if the Complain would have done within 45 days the germkit would have been replaced for free then the other person told same thing for 60 days.
I have started using pureit from Oct 1st and how come 1500 ltr germkit got finished in 20 days. I fill the pureit only once daily so at least it would have worked 3 months.

I cannot expect such responses from company like HUL. I would never buy any HUL product in future and neither recommend it to anyone. It's much better to use local assembled RO. My father was not in support of purchasing the pureit but still I convinced him.
I have received call from customer service provider that they can't provide any resolution to my problem. This is very frustrating for a customer that after following up several times a positive resolution is not provided.
