If you have any doubts about the legitimacy of a charity, like the Epilepsy Foundation, go to CharityNavigator.org where they give all the details on hundreds of charities and they do list ones they feel are scams.
called I answered, no one there...I found that any number calling me that I DO NOT KNOW I always answer with some thing like town hall, police quarters, morgue LOL They hang up and don't call back!
