Kerala Water Authority — Today is the fourth day when we didn't get water

Sir
I am from Manjummel, near Kalamassery. Our water authority office is in Kalamassery. Today is the fourth day which we didn't get water. First they gave us water second day wise, then it changes to third day . But today is the fourth day. They told me that water will come at 4 pm. But they didn't. When I call them again they told me that water will come at 6 pm. But no. Now it's 9.30pm. My family members including my small baby is waiting for the water. We dont have water for drinking too. Please help us.
