I would simply explain to him that you had both agreed to these terms, he did not follow them. So to avoid a possible scam tell him he is going to have to wait. You two are talking on the phone so it sounds that both parties are legitimate, we know your side is at least. If it never shows you will be thankful you did not send yours. If his shows than follow through on your end. As P.O.'d as he wants to get he didn't follow the agreement. His fault not yours.
