There are many drawbacks regarding to the gas agency :
1) The list of new connection is not displayed on the board.
2)No compliant book in the office.
3)The agency worker have no uniform so that we can not identify who is
the responsible person.
4) The time of agency is 10 to 12 and 4 to 6.
5) At agency there is no responsible person to handle the matters
