I highly suggest that people file disputes. If you don't end up getting your money back afterwards, file for mail fraud as well. If you win the dispute, but don't get money from the account and used a credit (or debit?) card you can try and file a charge back through your credit card company to get the money back.
EDIT! If you used funds transfer from a bank account, call your back and see if they can get your money back! Mine said an ACH claim was easy and would require paypal to give me my money back.
Edit: I googled and found some links for filling for mail fraud: http://gothicauctions.com/?c=FAQDisplayEntry&i=57
I purchased a crimson ds from her and have been getting the run around on the item being shipped/getting a refund. She even deleted posts and comments about items in her journal, which is on the skectchy side. She posted in several communities that some of you may visit. Has anyone who bought from her gotten their items or even a tracking number?
