Delhi Jal Board — exaggerated bill

Address:

D 35 A 2nd floor Vijaya Nagar Single Story Delhi, New Delhi, Delhi, 110009

Hello
I stay on rent in d 35 a 2nd floor vijay nagar single story
So far nobody has come to take the readings of meter from april i guess and in april he came after 3 years
In april we inquired about the bill and it was around 45000, now i came to know about that delhi government will waive off part of bill amount so for the same i inquired and i was told that bill amount is 70747
Now no-one has come to take reading of the meter, nor any bill had given me meanwhile, but they have arbitrararily increased the amount like anything.
Please look into the meter and provide me detail what amount i am supposed to pay after the deduction.
