FriendsCan someone provide me a list of STVs (Special Tariff Vouchers) applicable for the Kolkata circle.I remember seeing this info on their website once under prepaid services > tariffs > voucher rates, but now I can't them anywhere on their website.I have also sent emails to their CC, but they are not of much help anyways.So if anyone can list the STVs or point me to a link that has an updated list, that would be really helpfulMany thanks!
