I left Feedback for the wrong buyer--help!

[ajgsanfran]

I listed and sold three toys that are similar.  One of the buyers has not paid but somehow i left positive feedback, as though he had paid.  I thought I was posting to one of the other two buyers who immediately paid.....  not sure how the feedback page let me do this!

I can't get his attention to pay, by the way, to pay me....   I do not want to leave him negative feedback yet but I think it's unfair that he has positive feedback having done nothing but clicked "buy it now", since in the meantime I'm stuck with my item not being available to sell.

Is there no mechanism to rescind the positive feedback until he completes the deal?

thanks for your help.
