Power failure

My two younger sisters will appear in the HSC exams this year which will start from 16 April. Now it is their last revision time, so they need to study a lot, but they cannot. No, not due to family work, even they have no personal business. The problem is ELECTRICITY.
They live in Islampur village under Faridganj upazila of Chandpur district. Every day the electricity goes after 7:00pm. Then the supply is not restored before three hours.
Not only at night, load-shedding is taking place at midnight, even at noontime. It will have an impact on their results.
The problem has to be resolved on an emergency basis to save our students.
