The resort is most definitely undergoing a refurbishment. The current permits for construction expire at the end of April 2018 but at the pace that the work has been happening, it seems like it will take longer than that and the permits will be extended. You can follow the progress on
this thread (post #2 in the thread will indicate which buildings have been completed and which ones are being worked on.). Disney most likely won't update their pictures until the refurbishment is complete. And phone cast members consistently give out incorrect, outdated, and inconsistent information. Some times that is because they simply don't know or don't have the information and sometimes it's just what they've been told to say if someone asks. The person you talked to may not have had the correct information, or they may have been told not to indicate that there are renovations taking place as that might cause people to not book a room at that resort.
