Msrtc — Wrongly charged bus ticket

My father is a senior citizen 1937 born. At 12 56 pm at Chembur he was wrongly charged 515 rupees from Chembur to Pune. He has an aadhar card and driving license as forms of identification. The conductor at Chembur refused to accept his aadhar card and wrongly charged him 515 rupees instead of 10 rupees.Please refund excess amount 505 charged.
