Delhi Transport Corporation [DTC] — I was charged more for my total fare

Address:

RK puram Sector-8

I was traveling from RK Puram sector 8 to South moti bagh which is one stand far away.
I was in a AC DTC bus. So i give a 20 rupees note to tha conductor and also stating that I want a 10 ruppees ticket. But she gave me a 20 rupees ticket and saying that I had said to her this that I want a 20 rupees ticket.

I said her i am a student, 10 ruppees matter me the most but she replied that is fine your parents will provide you the money.
Also she does not provided any help to me .

She was covering her ears and face with a cloth. So it's her fault that she didn't hear me clearly.

My ticket number is 81903.
Kindly provide me the help and make sure that no other student falls in this scenario or a trap.
