Do you have a confirmation of purchase message in the 'Messages' tab on your account?
Did you purchase directly from the website here or through Google Play?
If it is the special offer through Google Play, there are some problems happening with that offer currently and it is taking several days for the purchase to be processed and received on to accounts.
