I want to give him a chance to make a statement on this. If he doesn't reply or refund my money I will red-flag him at a later point. Thanks for your advice.
He's seen the thread and is now
trolling around.
If he hasn't already, he's probably about to try to convince you that he can still get all your money back, and he's not a scammer - there was a misunderstanding or he was too busy saving someone else way more money and if you just give him more time he can help you....as long as you stop calling him out in public.
