how do i contact facebook directly?

[Samantha W]

I have a problem and i need to contact someone at facebook, a developer or customer service type person. I need to do this as i want to report a problem and i want an answer from facebook. Does anyone know how to do this, i have searched all the help centre and cant find this anywhere.
I do not wish to discuss the problem here for answers,
many thanks for your help
its more that i dont wish to openly discuss the problem on here. All i want is to get in contact with someone on facebook via email so that i can report a privacy and security issue and abuse so if anyone knows how to do this then it would be much appreciated
thanks
