Delhi Jal Board — despite the mutation, water bills with no.,[protected] still reflect the name of previous owners name

Address:

New Delhi, Delhi, 91

My name is tilak raj resident of 315 mig flat, prasad nagar, new delhi and having my kno is[protected], zone wz2 mr no 122 area a-6/rajendra nagar.
I had got the name of previous owner ie shri r. V. P. Raman mutated to my name ie tilak raj and the water bills started coming in my name also,, but after few months the water bills are reflecting again the name of previous owner.
Hence, i would request the concerned authorities of delhi jal board to correct their records and indicate henceforth, my name in the water bills instead of the previous owner.. The wrong name in the water bills is causing a great confusion and with the result, water bills don't reach me.
Thanking you,
Tilak raj
