I need to alter feed back. It was left by mistake. While trying to leave feed back for another

While trying to leave feed back for another seller this stupid auto gave it a positive feed back. It should have been a NEGATIVE.

I want to change it to correctly record the NEGATIVE not the Positive.

You cannot.

Only a neg or neut can be changed to pos provided the seller sends a revision request.

Not the other way around.
