Indian Railways — Overcharging at car parking

Address:

Shimla, Himachal Pradesh, 171009

I parked my vehicle at chandigarh railway station parking on 8.6.16 5.30 pm for my onward journey to new delhi. The rate is rs20/- per day. I was told to deposit rs.60/- as parking fee for the period from 11.30 am 8.6.16 to 11.30 am 10.6.16. I was told that it comes out to be three days whereas it was two days. 8th to 9th and 9th to tenth. But the person charged for three days saying that it is three days, thus overcharging.
