Right.  That means that your card failed the test.  It's standard practice in many companies -- Linden Lab among them -- to test a new account by making a nominal paper charge against the account and then reversing it.  No money actually changes hands, although the transaction will show up briefly on your account as a charge followed by a refund, if successful.  The point of doing that test is to be sure that your payment method is capable of sending and receiving money instantaneously.  Debit cards and most prepaid cards will fail the test because they cannot receive cash in on-line transactions.  So, that's what seems to have happened in your case.  I suggest registering a verified PayPal account as your payment method instead.
