May have quit the game. Isn't responding to messages, and hasn't seen them because he hasn't logged in for several days.

already I tried to communicate with him at the game facebook any more answer.

At first I couldn't add him as a friend, it took me like 5 days until he accepted my request, and when the time for trading was done, I contact him and he said that he no longer have the pet, he said I didn't contact him so he lost it. We made I trade, I didn't  contact him until the time we needed to wait arrive
