I had Pan/gir number and later received a Pan number which I have been using since 2004. While filing some registration paper I have been told that there is another Pan card issued to my name and cannot do anything till that is sorted. I have never received this card but online it shows as active. this has become a deterrant in my registration process. Please advise what I should do to cancel the second card as I do not have either the car or the details. thank you.
