As Monty said, generally they only give that kind of info out in-person at WDW.
But, I *have* heard one or two recent stories of people calling and getting the status of tickets. Perhaps with the Ticket Tag (finger scanning) system in place for all tickets, Disney is now comfortable enough with it keeping non-owners from using old tickets that they'll give the days-left info over the phone now?
It's worth a shot, at least. Give the Ticketing Office a call. They can be reached through the Main Switchboard at 407-824-2222. Then ask to be connected. (You do not want Central Reservations) And be aware that the Office has more limited hours than CRO. I think they're pretty close to M-F, 9-5.
Let us know if you have any luck!
