Pureit / Hindustan Unilever — Pre maturity expiration of germ kit

Address:	110053
Website:	pureit

Dear sir/madam, it is hereby informed that the germ kit of 3000 liter has been installed on 27 july 2016 and is exhaused on 5 october 2016 i. E. Only 71 days. Further it is declared that daily average water consumption is maximum 20 liters because there are only 4 family members and out of that 3 are working and we consume filtered water only for drinking, so according to this on an average only 1420 liters have been filtered but the germ kit of 3000 liters. Further it is declared that raw water quality is also good so how it has been exhaused so early... Please justify and resolve it as soon as possible.
I have called many times to customer care but they are not responding well and giving diplomatic answer.
