Can seller leave me negative feedback when he did not send item?

Question

I had a dispute with a seller. He never replied and never sent me my items.
Ebay intervened and I was refunded.
I still feel injured about the situation and I want to leave negative feedback to alert other buyers.
However, I'm afraid the seller will retaliate and send me back negative feedback.
Can he actually do that, even if he is wrong, or since he never sent me my items, he demoved from the right of posting me any kind of feedback?
Thanks to anyone who can shed a light.
