@Isha : We contacted Gamesplanet to look into this problem. It seems that they have an automated algorithm to check out suspicious IP or contradictory information.
If you've got the email, please contact their support / do what they are asking, and you should receive the keys quickly! If you have more issues, let us know about it.
Edit : Reading your last post, I think there was an IP conflict or a greographical problem, so please answer their questions, these are mainly made to protect you
