Mahadiscom / Mseb / Msedcl — high electricity bill after 20 months

Address:

Plot No. 11, Maniknagar, Gangapur Road, Nashik 42213, Nashik, Maharashtra, 422013

I have received an average bill of about Rs. 730 per month for the past 20 months and suddenly for the month of March 2019 MSEB Nashik have charged me a very high bill of Rs. 2130.

I went to complaint at the local office and they threatened me that they will also charge fees for previous bills. Please help as i have never received such a high amount of bill and they also threatening for fines and fees for previously paid bills.
