The way it's been explained to me by Fidelity is, once the offer is made and agreed on, they send the info to Disney to confirm the points and details of the contract. That's how they found out about the pending cruise on that contract I bid on last week.
Now, Fidelity did say the person who does the verification process at Disney doesn't do that as a full time job, so sometimes it might happen right away (if they are doing the verifications that day) or it might sit a day or so.
But either way, I agree with the pp that the TSS should have caught this. How can they be selling contracts w/o knowing the details of what's for sale? There must be a process in place to verify what sellers tell them or this sort of thing w/b happening all the time since sellers might not always know exactly what the status of their contracts and points are.
I hope you can get this worked out, but you might have to let this one go if the points you thought you were getting are being used for that vacation, in which case the contract s/b worth less.
