suck up to a buyer, refund but dont process cancellation via eba to get the FVF back (you will have to wear that). cross your fingers and hope buyer does not leave a neg or neut. If they do its a defect (they may leave no fb). If you get a defect you may as well go ahead and process cancellation and get fvf back as your already defective.

Sometimes you can dodge the bullet and sometimes you cant.
