Address:

560103

Hi bmtc,
Date of incident:[protected]
Issue : i got bus at sarjapur signal, next stop of iblur signal to go mahadevpura flyover.in genral the charge is 19inr. But the conductor charged 20inr, mentioning that i boarded at agara junction. When i asked why he entered agara junction, he didnt even respond.
Bus was not full, he has enough time to issue the ticket.

Please take necessary action.
Desirable solution : expecting conductor not to repeat this again.
