My dear sir,

I have bought a smart card from kolkata metro railway vide card no.[protected] in the year 2014 or before and since then using the same for metro railway. Fewdays ago i have gone to the ticket counter to recharge the metro smart card, the counter person said that the card is not readable properly and have to change or replace the card.in that respect i have gone the station master of kalighat metro railway to replace the card. The station master rejected my request to replace the card and said that this card cannot be changed and advised to buy a new card again. I requested the station master to make necessary arrangement to refund the card security deposit amount of rs.100/- and i shall buy a new card. He refused to do so and said no refund can be given and while saying that he has given me a form for refund of balance available and suggested to make another 4 copies of photocopy from the outside as they do not have much forms in their store.
I requested the station master to take my request for refund of security deposit and the balance again. He misbehaved and said nothing just can be done. Moreover his assistances were rude and rough while speakinf to the public and said that this card is defective or not in good position to refund. I asked if there is any problem with the card its the responsibiluty of the kolkata metro to replace as am a valid card holder and moreover there mey be some wear and tear of the card fro usage for a longer time.
I being a resident of india wish to know that whrether do my goverment has this policy to forfeit the public money as i have paid rs.100/- as security deposit while buying the smart card? Or ministry of railways have given any such direction to the kolkata metro to forfeit public money by way of not replacing the smart card agaisnt the old one which i have bought.
Needless to mention that every this do have wear and tear issue and which need to be replaced rather asking for no refund as kolkata metro have taken the amout while selling this card.
My humble request to your good office to please lookinto this matter as most urgent basis and please arrange to replace my old smart card by a new one.
