A serious question

[JBR]

In using Facebook, I have encountered a problem and asked for assistance at the site: 
"Contact Facebook Support team and help center" (yes, an American spelling).

I received a nice response from a person called John Hack, who describes himself as 'Admin', advising me to "Feel free to message the group admin they are here to support users who got their account disabled or hacked, message us now for help!"  
Clearly a bit of a prat, pratting about!  

However, I do have a problem with Facebook which I'd like to resolve, but I can find no means of contacting anyone who can advise.  Clearly, this site which I tried to use is not a genuine means of contacting the people who could properly advise me.

Does anyone know of the best place to seek advice, as I can see no obvious means of reporting a fault?
