Tamil Nadu State Transport Corporation [TNSTC] — I'm complaining against the bus conductor and bus driver for their rude behaviour

Actually inbetween chennai and Trichy, there is a place called Tindivanam. I am in that bus. During this stop we people try to bought a water bottle. We gave 100 rupees for 20 rupees water bottle. When that seller try to give the change. The bus starts immediately even they knows. There is no urgency at that point of time. They did because of their ruthless behavior with no reason. We people shouted to stop the bus for collecting the change. Even that seller also try to give. But conductor take it as easy without any proper explanation. I felt really bad about our government servant. I hope you will take any actions regarding these staffs behaviors.
