Bangalore Water Supply & Sewerage Board [Bwssb] — bwssb billing

Address: 560029

Hi,
I reside in thaverekere since 20years with total of 3houses as rented one's, i always used to get the water bill of[protected]/- per month and usage used to be[protected] liters of consumption, but in month of january i've got the bill of 3797/- which is really shocking, when i check the consumption it shows as 91000 liters used..
I seriously don't understand are these guys playing fool, mentioning meter reading details as per their wish.. I didn't even have any function or anything to get this bill amount..
When i discuss with people, they ask me whether, am i running a hotel business or having a individual house..

I try to complaint over these guys or discuss over the call, none are responding to me properly.. I'm seriously very pissed with the bills..

I want immediate resolution on this..
