Vermilion, can you please either share your side of the story here, or pm an explanation to one of the admin team. If we don't hear from you, I'll Impose a posting ban until we decide what (if any) action to take on this.
In the meantime, please do not offer to sell or trade anything at all.
Thanks.
Please note however - the admin team, and site owner will not usually get involved in any disputes regarding swaps/sales. You always do this at you own risk. Involvement this time is only because there is an outstanding issue, and more things are being offered.
