Undeserved feedback

[saj12340]

I recently had to cancel a sale because the item was damaged during packaging. When asked the reason for cancellation by eBay, I gave this reason but the buyer has left negative feedback stating that I gave the reason "out of stock". While I understand his/her disappointment, I feel that the negative feedback was unjustified as I had been honest and correct in cancelling the sale of an item that was no longer in the condition I described at the time of listing. I have tried to get a feedback revision but the eBay app just states that I have no feedback that is eligible for revision. Is there anything I can do about this? Thanks.

did you contact the buyer first to see whether they still wanted the item even with the damage?

did you send them photos of the damage to prove you were telling the truth?

if you can convince them you are telling the truth they may agree to revise the feedback.
