Perfect. That's the absolute worst move that idiot could have made. You'll get it removed whenever they threaten, and you have a chain of diplomacy that eBay can see, but that chain has to include an offer for a full refund, including shipping -- PERIOD. We know it's a leap of faith to take the short-term negative (it will be removed, though), but you have no choice with a high-dollar item. If they complain and the price is $50 or less, I tell them to keep it with a full refund, but I've been in your situation with big tickets, and you have to stand your ground. God-speed man!
