I would like to inform i have taken possession of flat no. 136, kondli gharoli in september 2013, and my flat was closed for two years and now after december 2016 flat is used by tenant and now today 25th june i have received a water bill for rs. 40, 668/- from dda division no. Ed.14/dda sub div no.- iv upto 30.06.2019.

Please correct the bill because rate of bill is rs. 363/- pm, according to my calculation bill amount should be rs. 11, 253/ (31 months x rs.363).
