Msedcl - Excess light bill

Dear Sir,
I am currently residing at Alankapuri,Dahigoan, which is having electricity connection bearing consumer no.************. Today, I was shocked to receive the current electricity bill no.*************** for an amount of ****Rs. My Monthly electricity bill amounts generally range between *** to *** Rs. The bill for this month is almost ** times the amount of my regular bills.

I investigated the matter from my side to find out the error.Whereas you can see that even if i calucate ** month bill as per *** Rs rate the bill will not go above **** Rs .
And since I have previously paid the bill of **** Rs on ** March **** and **** Rs on ** December ****.
Despite that, now I have got **** Rs bill, how can it be.
And I have also noticed that this mistake has happened in the bill of Jan'** Month, the reading of Jan'** Month has been taken wrong.
For your information, here I am giving you information about how many units I have consumed every month.

Month Consumed Unit.

Aug'** - ***
Sep'** - *
Oct'** - *
Nov'** - **
Dec'** - **
Jan'** - *
Feb'** - *
Mar'** - **
Apr'** - *
May'** - *
Jun'** - *
Jul'** - *
Aug'** - *
Sep'** - **
Oct'** - *
Nov'** - **
Dec'** - *
Jan'** - ****
Feb'** - **
Mar'** - **
Apr'** - **

Except Jan Month bill even if you total the entire unit and the bill comes out, then the bill will not go above **** Rs.
Request you to do a thorough investigation and solve this matter, and if you have overpaid the bill amount then please refund it.

I hope my complaint will be resolved as soon as possible.

Thanking You!
Yours faithfully,
