You can ask if ebay will remove it and why you think it should be BUT you can respond to that FB and put Won 9/8 paid by Paypal 28 Sep 2012 17:39:30 ACST as seen on receipt

This is an example. You can copy and paste the info from the PP payment received notice

for the $10.49 they paid in total it would not be worth the cost to return to you at their expense to get the refund.
