Delhi Jal Board — my bill for 2020 is very much high

Address:

C-47, Ist Floor, Jitar Nagar, Delhi -110051

My kno no. Is [protected] and bill received in the month of apr 20 and units consumed was also mentioned on the bill... Everyone knows that due to lockdown since march 20, no one came to take any reading. This bill is incorrect, as in last more than 1 year, we never consumed so much water. My consumption is always below 20, 000 ltrs and you can even check last one year history. Pls. Review my bill and send me the correct one.
