Sir,
Still i have received bill with the old name of "smt. Krishna devi"
Although i have already submited mutation fee with all documents in "december-2014' at paschmim vihar office but still now i have received bill with the name of krishna devi,
After that i have reminder complaint logged with documents in djb mohan garden office on 23.11.2016 application complaint no.12061 n desk employee name was mr. Mahender
But still not name corrected bill
Now i request you please change my name krishna devi to rekha
Actual current owner name is rekha
Thanks with regards
