Delhi Jal Board — ill water supply in the locality

I am a resident of pooth khurd. I have been facing the problem of 'no water' since past 6 days. People and houses around us have submersible connections and have ample amount of water to waste. I don't have it and hence facing the problem. I had been to the delhi jal board in our area but they dismissed the issue saying we don't know anything. This is not at all expected from the authorities. No one is listening to the complaint. If it were their issue, it would have been their topmost priority. Why not the layman then?! Why not the common people? Please resolve the issue asap. I'll be grateful to you.
