Delhi Jal Board — heavy bill against the k no. [protected]

Really don't know why so much heavy bill is being charged against k. No. [protected], whereas only two members are living. I am really very disappointed with such unnecessarily bill from delhi jal board, however, upto 20 kl water is free on monthly based, being such type of subsidy this doesn't make sense the heavy bill is charged.

It is very request to you that generate a new bill against the k no. [protected] and my matter may kindly be resolve at kindness action please.
