unable to leave feedback for non payment

Sold fragrance to buyer  <removed> non payment, no commincation entered a dispute.  But I am unable to leave feed for this buyer - to warn other ebay sellers about this buyer...    My sold page - indicates that i need to leave feedback - when click on it it does not bring the item / seller up and i am unable to leave  feedback   ...  Any suggestion - its very very unfair !!! and people should be warmed of this seller, as they have only purchased 1 item previously.

 

Buyers be warned
