Private Bus — Bus operators are charging bus passengers illegally

I am ilyas kv.

Hello ;-
I was visiting to my wife house. Because, my wife is pregnant as 9th months.
When i boarded in a private bus from malappuram, kunnummal bus stop to kottakkal. It is a private bus from manjeri stand to tirur stand. They took illegal charges from me.
Old bus fare: 12 (Malappuram to kottakkal)
13 (Malappuram to changuvetty)

New bus fare : 15 : (Malappuram to kottakkal)
17 : (Malappuram to changuvetty)

But, the bus workers i was traveling with were charging me an illegal fee. This is punishable by law and is required to be accepted as a complaint.
Bus name : laila
Bus reg. No : kl 10 z 1318
