In August, she sent me a note saying she was starting on it; that was the last contact I had with her. On November 29th, I sent her a note on FA asking about progress and she never replied to it. Then once again on December 10th, I sent her another note on FA, thinking something had gotten screwed up in the big downtime the site had through the week before, and maybe she hadn't received the note. She didn't respond to that. A week ago, December 30th, I sent her a note asking either for some sign of progress, or a refund. I still haven't gotten a reply from her, and she's submitted many things since the con. She's been fairly active recently, posting art and comments, and has yet to respond to my notes, effectively ignoring my overdue commission.
I don't know how else to get in contact with her, and I don't want to publicly post complaints on her page. At this point I just want my money refunded; she can forget about the badge.
EDIT as of 10:50 PM CST
I would like to say I have been nothing but patient and polite in all of my notes and my e-mail to her, and even in private conversation about her when other people were angry at her for her tone or inaction. Taking that into account, I am immensely disappointed with her response to my e-mail. I hope she can learn from this situation and not put the blame on her customers for her lack of foresight, in the future. I feel this tone warrants a warning to would-be commissioners, though I'll call the issue resolved as I have received my money. Good luck to you, Seel, you can be assured I will not be giving you any more of my business in the future.
