Players always should make their best efforts contacting each other to arrange the trade accordingly. A Trade moderator is not here to force the trade when an auction just ended and both parties still have not figured it out with each other.
@Lavkush If you can't contact the buyer in the next few days, feel free to click on the report button under the post to let us know, a Trade Moderator will come assisting when he has the time.
Until then, take care.
Kind regards,
