[Resolved]  PNB — Refund of Deducted Money for use of ATM-cum-Debit Card

I am an ATM-cum-Debit Card holder [Nos.[protected] and[protected]Add-on Card)] against S/B Account No.[protected] with Punjab National Bank, Salt Lake, Sector-V, Kolkata-700091 branch. At the time of issuing the above card, the bank informed that “There is no annual fee for your card”. But on 14.02.09, bank has deducted Rs 200/- as annual fee for the Debit Cards.

When I mailed the concerned auothority (The Chief ATM/Debit Cards, Punjab National Bank, HO: 5, Sansad Marg, New Delhi 110001) regarding this annual fee they promptly informed me through mail :
“Keeping in view to provide hassle free services, expansion of ATM network and pacing with the advance technology the Bank levied an annual charge of Rs100/- w.e.f .01.02.2008, which is nominal as compared to charges being levied by other Banks.”

Later on, I came to know that the bank has not imposed any annual charge against use of ATM-cum-Debit card to some of my colleagues and in some cases they have refunded the deducted annual fee for use of ATM-cum-Debit Card. When I mailed them regarding this partiality, even after reminder, they are surprisingly silent.

Now my question is :

Why my deducted money cannot be refunded like others?
Whether the justice can be varied from customer to customer?
