Indian Railways — inappropriate parking charges & rude behaviour at two wheeler parking

Sir,
At indore junction, the contractor is charging excess parking fees. He had deployed goons and thugs who doesnt have uniform or proper id cards for the same. Parking fees prescribed by railways is depicted & attached screenshot shot for same. However they are charging excessive fees. For max. 24 hours railways had prescribed fees of rs 5 for a motor bike. However theese goons are demanding rs 20 for 4 hours. While questioned they charged against me. A rpf officer was witness for the same. His timely action saved me from these goons. He further requested me to file a complaint to station master.
