Iphone deleted contacts and synched with facebook?

I woke up this morning, and every single number i saved manually on my iphone? All gone. I have hundreds of numbers on the list now from facebook so it obviously synched however in the settings menu i turned all that sh*t off so it would stop doing it. Why has this done this and how do i get regular contacts back?

To Get The Regular Contacts Back This is Gonna Be a Pain In the But To Do But You Have to Add Them All Back In To Get Them Back

As Far as Why Its Doing It Check your Settings There May Be a Setting That You Have Turned On That Made it Do It
