Indian Railways — due at railway station bike parking

Address:	East Godavari, Andhra Pradesh, 533401
Website:	www.irctc.com

I parked my bike in railway station bike stand and took the receipt. The stand operator did not said anything about the stand. After 1 day i came to take my bike the person who was in charge before day was not there and the other person says to pay 120.
I said i could not pay that much. The person says pay and take the money.
Even the contractor was not in that place and he says it was a primary parking. The person who was before not said any thing about primary parking.
They even did not gave receipt after paying money.
Please help me.
