I will leave a negative feedback on his trust page tomorrow. He is an abuser who deserves a feedback. What do you think about it?
If I may be honest, I was waiting for them to give some response before leaving any feedback, wanting to let them give further explanation and whatnot, even though it's kinda a clean cut case. Let's say I was curious of what OP tried to pull out of their pocket. I saw them online after I posted my reply and they're online again today, so I think it's safe to say they just admitted their defeat.
I'll tag the account as well, so that future scam accusations they raised could be taken with a grain... a bucket of salt.
You are right on this when you post an allegation you should be ready to defend your allegation and be more than willing to prove your case and provide all the pieces of evidence to strengthen your case and back it up as soon as you read the questions and concern, ignoring them will give suspicion on your motives.
They may or could create a new account and do the same thing hopefully we can trace them or do the same mistakes again
