Why do you think they are will call? As far as I know, all RZ (and GA) tix everywhere in the US are CCE, which is different (e.g., you never actually get any physical tickets at all--rather, you show the credit card you bought them with, and are let in immediately). Supposedly, if they are CCE, there is no way to sell them to anyone else, period (except maybe 1 ticket to whoever you're going with--and you yourself would still have to attend/go in yourself). Of course, lots of folks (like yourself) are in difficult situations, precisely because CCE tix cannot be sold or transferred (except the "plus one" thing as above), and the moderators here are trying to work out some kind of solution.
My order page on my Ticketmaster account states: "Your tickets are being held at the venue's box office for pick up day of the event"
