If I ever have to call WDWTC to change dates for some reason (which I typically don't, because you can usually make this modification online) I always check the site for availability and pricing prior to placing the call. That way, if the CM is quoting me something different than what I'm seeing, I can let them know and they can either re-check their dates and quote or get guest services involved. The training and knowledge of the CMs at the call center is so varied. I've spoken to CMs who seriously know their stuff and their way around the system. Others, I don't think have ever stepped foot in a WDW resort. OP, I certainly hope this works out in your favor and can certainly understand how frustrated you must feel.
