eBay crisis

Help! I somehow listed one item twice...no idea how or why. I'm looking through ebay help but I can't find how to cancel this! Anyone? Anyone?

UPDATE: Ding, I think I know how this happened. When I tried to list the item the first time, I got an error that said "request cannot be processed" so I logged out of ebay and tried again. I guess I shoulda checked my current listings before I listed the item again. Damn it! Emailed eBay and hopefully someone will write me back soon.

In the meantime, let it be known that I am selling my childhood on eBay.

UDATE: Hurrah. Got on Live Help and a very nice Mark A. helped me out and will be refunding my listing fees. Turns out I had to end both auctions b/c they somehow were both screwed up. The second listing was showing on the auction pages, but wasn't showing in my fees, which means somehow it wasn't really listed. Fucked up. But now everything's hunky-dory and my fee refund should show up tomorrow. *crosses fingers*
