Bangalore Metropolitan Transport Corporation [BMTC] — unfair extraction of penalty

Address:

ITPL BackGate, Bangalore, Karnataka, 560048

Today at 8:15 i had boarded a 305s series bus (Ka01 fa490) from mvjce college.
The bus was crowded and i was on a call for a few minutes which you can confirm from the video cameras.
At 8:20, the bus reached hopefarm and i got a seat and was asking the conductor for the tickets.
Hopefarm being a check point, a ticket checker, nandish kumar k. S, got into the bus and i had to pay him 190 for no reason whatsoever.
Just 5 minutes had passed and i was going to richmond circle. The ticket checker did not listen to anything and instead threatened taking me to a police station.
I hope you would look into this matter and provide a valid solution.
