OP made a mistake and couldn't cancel because they didn't have the email link?
OP also seems to not have made an Orbitz account that tracks bookings.
OP also seems to not have called to speak with Orbitz to get the resolution they wanted before the stay.
While I do agree there should be some form of action for rejected emails for confirmations but the onus is on the booker to input correct information & if they want to make a change they have to do more than just look for an email and give up.
