Telangana State Road Transport Corporation [TSRTC] — Telangana State Road Transport Corporation [TSRTC] Extra charges collected by ordinary

I have travelled from jntu to 4th phase. The conductor has charged total amount of rs. 20.00. actual ticket price is 15rs. She gave me ticket from jntu college to TCS building. This route conductors don't know the charges and even they can't listen properly. They give next stop tickets n collect extra money from us. They argue with us this is exact price this machine is showing this price. We travel daily with 15rs charge but they argue this is exact price.
