With the gift2go cards you will get the line like you said:
"8/23/2008 5:38 PM Purchase PAYPAL INC 402-935-7733 US -1.95"
Wait usually 2 days and re-log into the credit card account.
The expanded use 4 digit number should appear in the place of that line.
I have had this happen to me a few times with that card.
And I have always gone back a few days later and it was there.
Did you load the correct user information on the card through the web site before you used it?
If not that might be the flag that popped up....
I am not really sure yet why it does it that way.
