Delhi Metro — Exploitation at exit gate

Address:

New Delhi, Delhi

I travelled from Hauz Khas to New Delhi on 4/9/15 and used smart card to travel.My smart card had a balance of Rs.2.4 but I was not aware of that but the entry gate opened at Hauz Khas metro station and I didn't take notice of the balance .So when I tried to exit on New Delhi Metro station the gate did not open so I checked the problem with the lady sitting at customer care reception. She told me that I have "Zero balance" and it could not be the case that I entered with that smart card in Hauz Khas. She also refused to recharge my smart card and asked me to pay a fine of Rs.100 which I consider is totally unjustified.Eventually I have to pay Rs. 100 in spite of no mistake on my side.
