Respected sir/ma'am,

I'm sk anwar 6/2-a gholam jilani khan road, kolkata 700039.
My consumer no is this ([protected])
The electricity bill that i received of march 2017 appear to be much on the higher side, my average units 30to 50 usually stay between is180 to350 last 4-5 years. But the bill of feb and march 2017 was rs1380/- for units 203 which shockingly higher than the usual. Which is absolutely impossible. It is very difficult for me to pay but i paid for it due to customers care i talked they told that may be new meter (Old meter has changed) but it is too much because after changing its jumping very fast in 20 days it's over come 186 units it's shockingly for me how is possible i know my consumption.
There must be some fault with the meter
I request the concerned authority to please look into this matter as soon as possible and take necessary action.
Thanks and regards.
