Digital games are different. On PSN you have to technically add funds to the account and then buy the game.
When you preoder it'll ask you if you want to add $59.99 to your funds and buy the game.
When I preordered MLB 14 on PS3 (and any other game) it shows as a normal product purchase, but the product is a preorder. Same for Steam and other digital preorders. Then when the game is available the system makes the retail version free on your account, so you then make a 2nd purchase for $0.00 which is the game.
I believe you can cancel a preorder by calling Sony, I've heard of people doing that. But once the game is released you cannot get a refund.
