Delhi Jal Board — ZERO water supply

I want to file a complaint against Delhi Jal Board. My complaint id is[protected]. I have less water supply since weeks and NO water supply since last 4 days. A couple of days back I faced the same problem of NO water supply, my complaint id was #[protected].
This is a very serious concern. I live with my aged parents and my brother. We all have been suffering for days now. I have visited the Delhi Jal Board office, Tagore Garden twice and have spoken to multiple people over call. They either try to postpone things to tomorrow or stop picking up my calls.
There is not even a drop of water since days now.
It is impossible to live without water and seems like me & my family are being harassed.
I understand there is pandemic and our country is suffering. However, water is an essential commodity and not a luxury.

I request you to kindly take action as soon as possible.
