I sent FG to the wrong person and they have been ignoring me all day. They have been online all throughout the day and I’ve sent 3 messages. What do I do in this case?

If you already contacted the user and they are not responding to your messages after a reasonable amount of time you can open a topic in the Scammer Accusation section: https://forums.d2jsp.org/forum.php?f=250

Thank you for the quick reply!
