Ebay problem, how to handle?

[Mike in Vt]

Long story short...auction was for a 1966 Topps Joe Morgan. I received the card and on the back was a banner at the bottom saying it was a 2005 Topps Rookie Cup Reprint. I contacted the seller and simply said, "the card is a reprint and not original, I would like a full refund please".

The emails in response from the seller:
"No refunds, all sales final"
"I never listed the card as being original"

The case went to the Ebay Resolution Center where it was found in my favor, in a hurry. Ebay will grant me a full refund. The seller then contacted me today and said, "I would like you to remove the negative feedback since you won, I don't want to tarnish my perfect record. You still have my card anyways".

First, who cares if I won the resolution. Does that really matter? they still handled it in a very devious unprofessional panner. I don't want that card. It's literally not worth the stamp it was sent on.

Should I remove the negative feedback?
