Address: New Delhi, Delhi, 110019

Govind singh my connection kno no. [protected]
Bill no.[protected]. Amount. 2232/-
Please do something for this how it can this much amount because we do not use much water. This is first time i am facing a big mistake from delhi jal board
First i didn't get my bill as usually i get at home by courier/post
I went to collect it. And i am shocked to see this big amount for 74days and 51 units, i am very disappointed because last time i paid 732 for 53 units for 64 days. Please take a necessary and immediate action on this serious matter,
Thanks
