Bangalore Water Supply & Sewerage Board [Bwssb] — No proper water supply to our house

Address: Basaveshwara nagar, Bengaluru

Respected Sir,
We are facing shortage of water supply from past 3 months. Today I compalined to the inspector in the water board also. He sent the valve man and he saw that we were not getting water while the rest houses in our area were getting water.
Actually our house is int dead end and it is in the elevated place. We will not get water if there is no pressure. From past 5 years we never had any shortage of water supply even in summer too.. but from last 3 months we are having problem, valve man observed 2 months back that if there is pressure, we get water otherwise we won't. He checked at the meter also and confirmed that there is no problem in the meter.. and there is pressure problem, then after complaint he used to open the valve so that we were gettig water some days when there is pressure and no water when there is no pressure. Even our neighbours said that they are not getting enough water as they used to get earlier
Today even after complaint, He didn't released water, I called the valve man and requested him please leave water with more pressure, he said he will..but NO he didn't..Inspector didn't bothered to call us whether our issue is resolved or not???
WHAT SHOULD WE DO NOW? WHOM SHOULD WE CONTACT?
I HAVE ALL THE BILLS WHERE WE USED TO PAY 1200 ALMOST EVERY MONTH.
PLEASE RESOLVE OUR PROBLEM AND KINDLY OBLIGE
