While bidslammer says that I won this item, I didn't get any indication that I actually bidded or won the item. On ebay, it just says that the bidding is closed.

Hello Chris,
Thank you for your question about your bid. eBay rejected your bid because you haven't filled out enough information on their forms. The error says,
"In order to proceed, please provide additional details about yourself. Go to ebay.com."
Thank you for taking the time to write in. Please let us know if you have any other questions. We are happy to help.
