Tinky Deluxe

I recently bought land from someone i know others have bought from as well with no issue. He did ask me to pay him directly not through a box, and I did. After he tells me to wait he is giving me land rights then he goes offline 24hrs later I see him and asks he ignores my messages. I had a friend message him and he tells them he never go the money. She showed him my transaction history and he stops responding to her. Im so upset any suggestions
