331 panchantala tollygunge kolkata-41

Dear sir/madam
I use only 4 LED bulb, 2 fans and a tv.
My monthly bills are as follow:-
1. One year from nov 2018 tonov2019- Rs2229.00
2.Dec2019- Rs270.00
3.Jan2020- Rs120.00
4. Feb2020- Rs120.00
5. Mar2020- Rs150.00
6.Apr2020- Ra0.00
7.May2020- Rs 0.00
7. Jun2020- Rs170.00
8.July2020- Rs1610.00
9. Aug2020- Rs1110.00
10.sep2020- Rs1550.00
And my monthly reading is average 20 units.
By seeing above figures it could be understood that monthly bill of July 2020, Aug 2020 and sep 2020 is wrong.

So you are requested to provide the monthly meter reading from January 2019 to se 2020, and also give the reason why my july 2020 aug2020 and sep2020 bills and meter reading is so high.

Thanking you
