If you purchased an item and received a purchase submitted message on your screen but have not received a confirmation email, this means that your purchase has not yet completed and is currently in review. Purchase notification emails are sent to the email address on file once the purchase completes. Once the purchase is captured, or if the purchase attempt is declined, you will receive an email notifying you on the order status.
It’s possible it may take a few hours for your purchase attempt to complete. For more information on the timeframe, please review this article.
