Withdrawing feedback given

[wattiesdad]

I accidentally gave feedback on an item that was cancelled by the buyer, how can I retract it or change it? I know changing it (if possible) will still leave positive feedback, but I'd rather that and tell him what I think and let others know, rather than him having a nice comment.

positive feedback cannot be revised.

If you leave a follow up that's negative in any way it can damage your account.
