My company wrongly attacked by Ripoff Report; they want $$ to remove it. ROR shows b4 my own co. on Google search. How do I stop it?

If you can prove that what ROR posted is not true -- and that you proved to ROR that it's not true -- and they still refuse to remove it, and they have asked for money to do that (surely they weren't stupid enough to make that ask in writing or an email?), you have a very good case for defamation, and the demand for money, to make a retraction that should have been done automatically on proof that they were wrong, will be something a good lawyer can use to prove malice.  And malice can mean punitive damages, over and above any actual financial injury to your business that you can prove.
