Responding to Unfair Negative Feedback

[blwhatacollection]

Yesterday I received a complaint from a buyer who claimed the vinyl record (LP) he bought arrived "warped." I tested the item before shipping (which happened within 24 hours of the LP purchase) and it was not warped and played perfectly as advertised.  So, a day later, when the buyer claimed it was "warped" I remarked that it had been perfect when it left me and that vinyl LPs don't generally "warp" in transit.  From the beginning the buyer was extremely rude and adversarial. Despite that, I refunded the purchase price but indicated that my policy is not to refund shipping.  A refund was issued within an hour or so of the initial "complaint" by the buyer.  Frankly, I don't believe there is anything wrong with the record but I decided to take the high road and issue the refund.  I went to bed and the next AM the buyer had reported me to ebay for not refunding the shipping fee.  So, despite my feelings that this whole claim of "damage" was bogus, I also refunded the shipping.  More nasty, rude emails came from the buyer.  Finally, he left negative feedback.

Back in the day, a seller could respond directly to negative feedback and at least get his/her "side" out there.  I have nothing but positive feedback and I am a good, responsible seller so I am really, really upset that one bad apple (who I actually believe made up the story of alleged "damage") can leave negative feedback despite getting a refund in record time.  Is there a way to respond to this negative feedback on my feedback page?  If so, I'm not seeing it.
