so basically i traded my haunter with a person as i wanted to evolve it. i pm'd the person and they had agreed but i closed the pm window.when i gave my haunter to him he said it was locked as he had not got the 8 badges of sinnoh region.i told him to get the 8 badges then return my pokemon and i had sent him a friend request and he had accepted it but then removed me from being friends. now i cant find them and i believe they have stolen my pokemon . the only proof i have is of msg of trade completed (in first picture) and then i aksed in chat for solution(2nd picture) then i sent friend request they had accepted it(3rd picture).they are not in my friends list as they have removed me from being friend(4th picture). please help me i am on gold server.
