I went first and gave him my code. He confirmed that it was working.
His code however wasn't working. After some discussion, he claimed his code was for EU n&e and not, as requested by me, for EU West.
He then said it was my fault for not saying it multiple times that i want a EUWest code, even though i gave him a link to my thread in which i request a EUWest code AND I also mentioned it at the beginning of our skype chat session.
Believing that it might really be an mistake, i offerd him, that he could simple pay for the code he received from me via paypal.
He didn't reply to that offer and is ignoring me since.
DO NOT TRADE WITH HIM, let my trust be a warning to him.
Regards 1ch.
PS: I am sure, that he will deny alot of this, but i have screenshots of the skypeconversation in case anyone wants proof.
