I got a shipment similar to that a few years ago, the leaves were completely dried out with no green on them, however, the root system was very good. Once they were planted they rebounded quickly. Here is a link to that thread.

Concerning the feedback, I agree with the others, and I would contact the seller and see what they say. I also agree that feedback should honestly reflect how you feel about the shipment and overall transaction, otherwise, it isn't worth anything. If you are uncomfortable leaving neutral feedback, I would not leave feedback at all, rather than post feedback that doesn't reflect my true feelings.
