Unfortunately, I think the promo code(s) is/are lost for good, though you can contact a BBY forum rep directly via PM and explain the situation in the hopes that you can get something for the trouble.
For RZ certificates, wait for 5-7 business days in case they automatically reappear in your account (I was told this might happen by a rep the last time I experienced a ghost order). If they don't, you have no alternative than to contact a BBY forum rep, explain the situation, and ask for your points to be manually added back to your account.
Remember: Assuming you used a BBY GC on the order, you should supply its number and PIN so the rep can verify that you were charged for the "nonexistent" order.
Ever since this happened to me with
Injustice (

) during its DotD, whenever I place an online order, I never close the tab containing the confirmation/order number unless I receive a confirmation email; if it turns out to be a ghost order, having the confirmation number should help to explain the situation to the BBY forum rep.
