Jack, First of all...Take a deep breath...
I know it's frustrating BUT you can do a few things to remove the 2 retalitory feedbacks he left you!
Read this as you DEFINATELY qualify!
http://pages.ebay.com/help/feedback/questions/retaliatory-feedback.html Follow the steps and BOTH retalitory negatives will be removed!
Then after you've gotten them 2 removed...
Try Mutual Feedback Removal for the first one! Read this...
http://pages.ebay.com/help/feedback/questions/mutual-withdrawal.html If he refuses the mutual removal then try ebay safe harbor...I believe they charge 20 bucks but they are good at reasoning with knuckleheads...haha
~Good Luck!~
