Indian Oil Corporation [IOC] — delivery guy charges extra

Address:

Vishnu gas agency, Mahadevapura, Bangalore, Karnataka, 560037

The delivery person from vishnu gas agency (Indane) in bangalore is very rude and charges extra everytime,. It's high time the higher ups of this prestigious organization take this up seriously. Inspite of paying online, they charge extra. Its not about money, it's about principles, i would rather donate to a orphanage than give these people. They have the audacity to argue and threaten you if not consent to their demands. I hope the heads of organization does something drastically.
Hoping for a positive response from the concerned department
