Gujarat State Road Transport Corporation [GSRTC] — misbehaving of conductor, charged more fair than printed ticket

Yesterday i was traveling from ahmedabad to palanpur through the gsrtc bus number 1930abddsaexp51. I have faced a very rude behavior of conductor. Ticket charge was 106 rupees, i have him 110 rupees and he did not returned the change amount of 4 rupees. During the traveling i asked him to return the 4 rupees, he rudely said i don't have change though he had chillers in his pocket which he got from other passengers. While getting down at palanpur i asked him again to return the change, again he said he don't have changed. So when i told him i can see the chillers in your pocket, then he hold my collar and will not return your 4 rupees. Do what ever you can.

I felt so bad and didn't sleep while night with that incident. Request to please do the needful in this regard. So that the conductor must realize his mistake and don't repeat this again with other pessangers.
