You first need to log out of this UK site, and log into www.ebay.com to continue.
Here in the UK once a case is closed another cannot be opened for the same item in eBay and we advise members to turn to their payment provider for help with their refund.
I don't know if this is the same in the States so best to ask Customer Services there how to proceed.
Contact US eBay Customer Services this way, through their help pages.
