Website Poofed

A couple nights ago I was in my admin panel approving held comments. I was moving very slowly in there, then all of a sudden, Poof, my entire website went down. I have gone back and forth with my hosting support. They did get my main url back up, but everything else is gone. They are blaming wordpress and instructed me to contact them.

After searching for a support number and not finding one, I came across this place. Can anyone help me please?
