Postseason fund for games not played

I bought tickets for the Wild Card Game 3 (Oct 3 game day). The Astros website says that "in the event that the series for which this ticket is issued concludes before the date on which the game was scheduled to occur, a refund will automatically be posted to the payment card used for payment of the ticket." However, I have yet to get a refund and I'm wondering for those who have bought postseason tickets in the past, how long did it take to get your refund?
