Indian Railways — fined in railway station and wrongly accused

Address:

602004

I searched for mylapore station in google maps and it shows me a direction and when i got to the destination, there are no ticket center as i thought it was upstairs but it is not there when i asked a passenger he showed the way to it and when i climbed downstairs the ticket checker asked my ticket, as i told her i was on the way to buy a ticket as she says it's not acceptable because you used platform, then only i realised the way which i came was back side of the station and i told her there is no sign or direction to the ticket center so i came upstairs and one passenger showed this direction, she doesn't get satisfied with it and she fierced me with the high voice saying i was accused and fines me. It is not fair i was going to buy a ticket only.
