South Western Railway — Parking ticket

Address:

Bangalore Urban, Karnataka, 560023

I had parked my car at basement of Bangalore railway station, back gate. after just 1 hour while i come near exit to pay the parking fee, the person asked me to pay Rs.30/- and he denied to give the receipt of the same.
Moreover there was no notice of the parking fee tariff anywhere.
How can be Railway dept be so irresponsible & work without a proper system.
Its like day light robbery done & public being its victim.
Will anyone take a charge of this illegal issue happening in Railway dept.
