I have purchased this flat from one shri.ANNAKESAVAN in1997 and residing here and was receiving &paying water per month as per then policy till 2015.The K.No.[protected].Subsequently Delhi Government exempted all house holds for less than 20 kl/month consumption.we were exempt and no one came to us, no bill or any notice of malfuntin ot meter was given us.
IN MARCH 2019 we were sent a bill of Rs.3 lacs. Bill no.[protected] dt24.3.2019.We were shocked.I personally went DJB R.K.Puram office.They said our meter is not working and as such total arear bill is to be paid.To ensure the facts and my pleadings to them, I took meter reading on following dates-
1)03.04.2019...1249.86
2)09.04.2019...1252.24
3)19.06.2019...1283.81
Total consumption for 75 days...34KL or monthly 14kl.which is in exemption category.Our entire bill of rs.3 lacs be exempted and officials responssible for our harassment and mental agoy b sevrely punished so tha other citzens do not suffer.
Thanks, expecting early justice.
