Ebay debit the final selling fee to your ebay account as soon as the listing ends with a winning buyer not when the buyer pays.
If the buyer doesn't pay you have to make ebay aware in order to get a refund of the fee.
You can open an unpaid case 2 days after sale ends (though some sellers leave it a bit longer) and then close it 4 days later if buyer still hasn't paid.

You get a refund of your final selling fee and non payer gets a strike on their account.
Neither of you can leave any feedback.
Then you can relist.
