I have complaint regarding my bill. I think its not correct amount its increased. Normally i get the bill of 110 rs per month but the bill you sent me of last three months (Jan, feb, march-2019) is increased too much... I just use 4 led bulbs and 2 fan only for two months and i also live in other state.
And the most important thing is the calculated amount is also wrong
I calculated the amount sum is 337.12 rs and you sent me the bill of 768.0 rs
