Tried to sell my gold and found a scammer

As the title says I tried to sell runewild gold and found this page Buying/Selling all rsps .
So I decided to check it out , sent a friend request , accepted all normal. I Decided to ask for 10m/b and the guy says 9 I then say 9.5 and he agrees.
Me starting to doubt I ask for middleman usage which he agrees but he wants to choose.
I am sorry to call you into this Devil, but they make a conversation with "him" (Original post ❤️[500+ Vouches] [215+ Trades MM'd]❤️[$300+ Donor]❤️Devil's FREE x SAFE x POGGER Middleman Service❤️). While we were talking I proceed to check ID's and woops wrong ones. After I point that they immediately kick me out of the group conversation and block me.
