You can always ask ebay for look into to removing the negative feedbacks. I've gotten a couple negatives removed after getting them from stupid sellers and buyers before. The seller would have to agree to this though. You might have a bit of luck with it though since it's obvioulsy retalitory feedback. Two of the negatives have nothing to do with the item in dispute. I'd at least bring that to ebays attention since I'm pretty sure it's against ebays policies.
