What do you do about Facebook disabling my account?

Hi everyone,

I am a theater teacher and founder of a company. I use Facebook to promote my business in Chicago. I wanted to know if anyone has encountered issues with your account being disabled from Facebook? What do I do? I'm extremely disappointed that they deleted it without any notification. Does anyone know of a way to contact Facebook directly? I would appreciate any moral support. My event is tonight at 6:30 p.m. and all of my contacts were through Facebook and the companies NING account.

Thank you for your time,
Sydney
