Uttar Pradesh Power Corporation [UPPCL] — bill with the wrong amount and details

Address:	Lucknow, Uttar Pradesh, 226010
Website:	www.upccl

Ac no- [protected], i have always paid my bills on time, online. I have the copy of the same as well. In february, i checked my bill and it was of Rs 11559/ i was shocked, and i didnt paid the bill. I live in a rented accomodation. I visited your office as well, they told me the meter has generated some pending units this month. I am a qualified person who understand the things. How metre can generate some pending units after 10 months ? Lets suppose yes it can generate, in that case i paid my bills on regular basis without any fail, then how cum this much difference? How can i understand this pending units are of the months i shifted? This much amount never comes in resedential area. The point is not about the amount but misleading to a wrong information.
Kindly resolve my issue, so that i can proceed for the payment.
I am attaching the screen shot of the payment details i made in december 2017.
