Dear @hanumantha1122_kune,
You were charged Rs. 313 instead of Rs. 303 for your Bangalore to Rayadurg bus ticket. Could you please confirm if you traveled with Karnataka State Road Transport Corporation (KSRTC)? If yes, you can call KSRTC customer care at 08049596666 for help.
If it was a private bus company, please contact their customer service to clarify the fare difference.
If you still need help, feel free to reply to us.
