South Bihar Power Distribution Company [SBPDCL] — high voltage everytime and everyday 280 to 300

Address: Fazalganj, Sasaram - 821115, Bihar, Rohtas, Bihar, 821113

In Takiya Area, Sasaram (821113), Rohtas district, Bihar electricity power is always high and no one work on our complaint, so that's why I complaint here. In bihar voltage standard is 220 to 240 Volts, alternating at 50 cycles per second but in Sasaram maximum time Voltage is 280 to 300, so that's not a good sine to work like this. And no one guaranteed our home appliances when over voltage damaged our product. And I pay my electricity bill on time so I expect that 'SBPDCL' provide me a standard voltage.
