We recently booked a Wishes Desert Party for August 1st. The next day our credit card company called to inform us that over $500 had been charged to several different stores. I called to let Disney know what had happened and they did not seem to care. I only called them so they would be aware that someone had stolen the numbers and used them to make purchases.
I'm very sorry to hear this happened to you. I hope your CC bank can get it all cleared up soon for you & you have a great trip inspite of this violation 
Visa took care of it rather quickly and I do monitor my stuff to ensure that my identity hasn't been completely stolen.
