I used to train the Disney Reservation Center (DRC) Cast Members. Between classes, I answered calls. I completely understand why guests get upset over conflicting information. But, the assumption that it's always the DRC Cast Member who is responsible for the false information is a bad one. DRC agents verify information using an intranet site. The same piece of information can appear in multiple locations on the intranet. In my experience, it wasn't uncommon to see conflicting information. But, you'd only know it's conflicting if you look in two places.
Undoubtedly, there are poor DRC agents that assume they know the answer and fail to verify the information they provide. But, please don't assume the worst of a Cast Member. Chances are good that if you're given conflicting information by a DRC Cast Member, it's not because they made a mistake. They are only passing along the information to which they have access.
(For the record, providing conflicting information is never okay. It's just a pet peeve of mine to see my former colleagues continually getting blamed for this problem.)
