eBay isn't going to do shit since you're refunded. As far as they're concerned, everything is fine.
I had some dickhead in Canada try to fuck me when he purchased a set of golf clubs from me. After attempting to say they weren't in good condition, rusted, etc, he wanted me to give him some money back. Instead, I took it to eBay and said "listen dude, here's a full refund send my shit back" and he got all antsy because he realized that eBay would enforce that policy no questions ask.
Long story short, dont be flakey. You didn't lose your money and be happy about that.
