South Bihar Power Distribution Company [SBPDCL] — company is charging extra

Address: Patna, Bihar, 800004

The company from last year is charging nearly rs. 185 extra everymonth in the name of excess demand charge.
Its been years since the electronic meter has been installed but now a days the company bill dispalys excess demand charge even after consuming just 50-60 units per month. To it reached its height when they have charges rs. 186 extra for consuming just 27 units in 28 days.
This is too much now. You guys seriously need to look in this matter and find a proper solution for this as you have charged me more than 20000 rupees extra till now.
