Jim,
You can file an unpaid dispute. Here you go.
Unpaid Item Policy
Buyers automatically enter into a legally binding contract to purchase the item from the seller if they win the online auction or use the Buy It Now feature. eBay's Unpaid Item policy requires buyers to pay the seller for the items that they commit to purchase.
Sellers can
file an Unpaid Item dispute with eBay for each of their items that are purchased but not paid for. eBay will issue a strike on the account of the buyer who does not honor their obligation to pay (unless the buyer and seller mutually agree not to complete the transaction).
Note: If a buyer gets too many strikes in too short a time period, their account will be suspended indefinitely. In some cases, limits may be placed on the buyer’s account in advance of suspension.
