You can file for mutual feedback withdrawl directly with eBay.
http://pages.ebay.com/help/feedback/questions/mutual-withdrawal.html
It will only work if your "buyer" co-operates.
Don't waste time and/or money trying through Square Trade.
Too bad you didn't file a UID, if the other party does not respond you can have their feedback removed (sort of) without their co-operation.
If not no big deal, I'm not worried about it
Good attitude (seriously), it will fall off the 1st page in a few days and you already have a couple negs so ther is no perfect record to protect.
I always wonder somewhat about a seller with thousands of transactions and still at 100%.....
