If you click on your history, and have purchased (either by web/phone/in person or via the ACS) you should see the fixture Newcastle United, with the status PEND (like Horsham Gull). This means the transaction has gone through, and the event is to be uploaded to your smart card. If you don't see this - and are thinking you have purchased, then you need to call the ticket office.
Well my status says "Printing" but I notice they have taken the cash out of my credit card account so assume aok.
