Delhi Jal Board — related bill

Address:

Karol bagh new delhi, New Delhi, Delhi, 110006

Dear sir/mam,

This is regarding my bill amount i paid my last bill on 30 nov 2018 and amount was 23 rupees next bill was generated 11, 773 on 6th march 2019 which is totally wrong in my family only 4 people. Kindly cross check reading nd meter can't afford this bill now my bill is approx 21k.
If for 4 month bill was 23 rupees suddenly it's not possible that bill can be directly 11, 773
Kindly look into this issue

Thanks
