Ebay don't give a toss - it's small beer to them and not worth bothering about from their point of view. Have you suffered a financial loss? - you might be able to take the seller through the small claims court, but all you'll get back is money owed. Compensation doesn't appear to be an issue either.
Look at the guy still trying to name/shame Tune-o-Matic - he alleges, and suggests he has evidence that they sold him a misdescribed bass and he is seriously out of pocket - Ebay aren't interested.
Just leave the seller stinking feedback and forget it - life's too short.
