Delhi Jal Board — wrong bill issued and the billing consistency is not understandable.

Address:

110032

I have an water connection in the name of "sharma, jitender" address -
27/69, g. Fgali no 8,
Vishwas nagar,
Shahdara - 110032
With kno no - [protected]
First of all please notice i am paying my water dues consistently on month to month basis but on nov.2016 i got a bill amount of 6262 although in a whole month i had paid my billing amount which is showing in your bill in paid month bill colum :-

Please take a note as i am a renter of this said connection since july 2014 and paid the water amount 1198 rs on 14.07.015 due to no water bill received on my address and after then the bill i have received is 0 rs, amount and in 2016 year as you see the detail also total 5 times i have received my bill and the same i have paid to delhi jal board consistently basis but i have surprised and shocked when on nov.2016 i have received a bill of amount 6226 and after the customer care inquiry i came to know that the bill reading is wrongly noted by the reading noted.
Now the question is - can a person take 5 times wrong bill and generate the same on the system else the authority person doing some wrong activity on my bill.
Some of logical fact based on your generated bill is as under :-
