Second Chance Offer Resulted in Unfair Feedback

I sold an item on the 6th March the wining bidder made no attempt to pay for the item or communicate for a payment extension.  So I opened a case after the 6th day of non-payment to get my final selling fee credited back to my account.  I then put the item up for second chance offer which the system allows me to do.  The item was once again purchased and payment made immeadiately. 

I then requested to the orignal bidder that I wanted to cancel the transaction through the resolution centre and which they agreed to do.  The next thng I see is they have left me a negaitve feedback which I believe is unfair as the way I see it I have done nothing wrong?

Perhaps my mistake was to jump the gun before the case closed and pushed for the second chance offer and now my rating has gone from 100% to 99.2%.  I think people will make decisions on whether to purchase or not based on these scores.  I did appeal but to no avail and now Im begining to think eBay is a bit biased in favour to the buyer .
