Indian Oil Corporation [IOC] — delivery boy harassing give extra amount

Address:

Nagapattinam, Tamil Nadu, 609111

Inspite of several complaints. No one is bothered to take action. The gas bill itself is 610 and how can they ask 30 rs extra on that every time. Open bribery. Why should we pay extra when it is already included.
Why is ioc giving licence to these type of service providers. Are these delivery boys not getting their salary. Why is this happening everytime how many people suffering vlfrom this paying extra 30rs.
I need solution not just automated reply...
