Make a statement or refund my money or I will publish a (false and misleading) scam accusation that will cause Game Protect a damage!
It's not false or misleading. You did scam 210 euro, and you made up a defamation claim as an excuse to not pay it back. If you suffered any damage it's because of your scam and your subsequent trolling, not because someone asked you to return what's rightfully theirs.
