I got scammed by a player named "Banktakfest" on my bank character "Pankkijaba" about ~5days ago.
A GM directed me here, so here goes:
I was selling my Fiery War Axe and we agreed on a price of 90g, then I opened a trade with him. I traded the item and he traded 90g, just after i pressed accept the price changed from 90g --> 9g. After this he went immediately offline and ignored all my messages/whispers. Now he has it in AH for 100g. I assume he was using some kind of a macro or script.
If you have access to my characters whisper/chat logs, you can confirm that we agreed on the price above.
Thanks in advance,
Keimu
