Negative feedback Woes

As a seller I take great care to describe my items as closely as possible and go to the trouble of including 3 or more photos of the actual item. This morning I received a message from a buyer - strongly worded - stating her dissastifaction with her book.

 

While I stand by my item description, I decided it was better to cut my loses and so I immediately organised a full refund. And then... I noticed she'd already left negative feedback.

 

Is it too much to ask for buyers to contact a seller first and try to come to some sort of amicable solution? It's a simple matter of courtesy, something this buyer is obviously lacking.
