Delhi Transport Corporation [DTC] — a private dtc robbing customers

Hello sir,
I'm a visitor from nainital and i boarded a private dtc bus from anand vihar isbt. I was going from anand vihar to delhi gate which is approximately 11 km but the conductor charged me 160 rupees for one ticket.

He charged the same to everyone and most of the people were daily wage workers and kids.
When one person denied to give them the much money, the conductor slapped the person 4-5 times repeatedly on the face.
When i inquired why it is so expensive his reply was rude and full of threat.

When i get off the bus, i tried to see the number but the number plate was cleverly hidden by a pamphlet.

I remember it was a mini bus, blue colored but instead of just a normal pain job, it has mural done with it, something like a peacock.

I wonder why this person is been allowed to operate and how did he get his permit considering he's picking up customers from the middle of isbt.

I hope you'll resolve this issue soon and catch the culprit.
