Load shedding and electricity bill

Within 24 hours we suffer 6-10 times from load shedding and there is no electricity supply for 4-8 hours daily.
We are however puzzled and we fail to understand the mechanism and logic as to how the amount of our monthly normal electricity bill is on the rise every month.
In addition to payment of increased amount of electricity bill we are required to spend a huge sum of money for purchase of costly candles and lantern kerosene to perform various domestic, commercial works and for studies of our children at night.
Would our Ministry of Energy, PDB and Dhaka Power Distribution Company the new wine in old bottle (DESA) kindly look into the sufferings and financial hardships of the common people?
We would request and suggest our authorities concerned to cut down the existing rate of tarriff of electricity by 30 per cent in view of price hike of essential goods and commodities and untold sufferings of the people pending improvement of unabated and troublesome load shedding in the interest of public service.
