Got Scammed. Looking for mod to help ban this user.

Hi got scammed by this user-

Im looking for mod support to ban him. I have some extra evidence in pictures.
I “sold” him a Kalos Wheel but me being dumb gave him benefit of the doubt that the fake gameflip notification was actually real. This is my first time being scammed. After I gave him the wheel he left and never payed.

This is the evidence of him scamming me.
