I really don't want to pick a fight (alright, that is not entirely true or else I shouldn't post ), but that is exactly the reason why ebay stopped buyers from leaving neutral or negative feedback.

The fact is, the bike is fine, there is no problem other than that you "disapprove" of the packing job. He paid for the frame, the frame is fine, people weren't bidding on how well the frame was packed.

Now if the frame was damaged because of the poor packing job, the seller should have the right to fix the problem before someone leaves bad feedback. If the seller makes good, the worst thing that happened was that you are disappointed you didn't get your frame - boo hoo, cry me a river.
