Uttar Pradesh Power Corporation [UPPCL] — Wrong electricity bill of Rs 1,25,000/-

Address: Meerut

My initial electricity account is - [protected] in the name of Suman
and I have been paying my electricity bills throughout.
My address is - 133 Dev Nagar Mission compound Meerut (Pin - 250001)

But now, the person came from the electricity department and said that your account ID is - [protected] under the name of Dr. Anil Kumar and said that due to some error the bill is now Rs. 1, 25, 000/-.

further, when I enquired they said that I have not paid the bill since 2019.
How is it possible that the electricity department is offering me free electricity from[protected], and not sending any notice?
Also, they said the electricity will be cut if I did not pay this amount.

Kindly look into the matter and resolve it soon.
Else I will have to take it to the court.
