I am very frustrated with the change in feedback, and vigorously opposed it in my emails to Ebay (as if it matters!). Like Carlos, my feedback score changed, although only slightly. I really depended on the negative feedback withdrawal because virtually 100% of my negatives have come from buyers who never notified me of a problem before posting! How could I fix a problem when I didn't even know of it? Ebay doesn't care about this kind of situation.
One thing that is not clear to me--are we still able to RESPOND to negative feedback within a negative from buyers? Losing that would be an enormous loss. Has anyone tried it?
