[Resolved]  Pure It Water Filter — replacement of battery

Ive purchased pure it water filter 4 months ago, now its time to change the chlorine pack. i called Mr Gopal at [protected] whoo installed filter, he gave me another no and said he will attend your call, the no he gave was switched OFF, then i call helpline where i was to to wait. after several times no contact can be made. I once again called Mr. Gopal and he again insisted to call the number he is giving which i refused. I just want to ask HUL person if they cant give timely service then why do they sell all this junk to people.
I will be using this filter bin as dustbin in the future and recommend others not to buy Pureit.
