My Schwab ATM rebates have always been posted only at monthend, and not at the time of the transaction. I received over $27 of such rebates recently after a trip to Argentina, where ATM fees are very high. Give it a few days, and you might be surprised to see some rebates posted over the weekend or early next week.
fwiw, I completely agree that it's extremely annoying that Schwab can't print a statement that includes the actual amount in local currency that you received from the ATM, which could be matched to the slip of paper you receive from the ATM machine. I match the transactions by date and location, but it is truly idiotic that no local currency transaction amount is included on the statement....
