Mahadiscom / Mseb / Msedcl — Incorrect average billing being done for 3 years, where house is unoccupied

Hello,
We do not live in our 1bhk flat permanently, as we have another house in our home town. But since last 3 years, for periods we aren't there, we are being charged a flat incorrect amount of around 460 rs. We are retired elderly people, and this amount over last 3 years period is a lot for us. Pls correct and also adjust.
