Delhi Transport Corporation [DTC] — regarding penalty charged on me

Address:

Andrews Ganj, New Delhi, Delhi, 110049

Dear sir,
This is to inform you that, i, mamuni kumari, was travelling on bus today, and i, caught the wrong bus. I didn't take the ticket because it was the wrong bus and had to get off to the next bus stand.
As soon as, i get off to the bus two three people charged 200rs as a penality. They were from delhi transit corporation. I was running out of cash, i asked them for online transaction, none of them had that facility. They gave me their friends number to transfer on that. They handed over challan in return to the payment.
I have issue with amount they charged and with the challan, because challan nither have any authenticity nor any stamp.
Kindly look into the case, if it is fraud case, then kindly take any action against this.
