Here's a number I found on a website called "Get Human." I was able to reach a live person at ebay after an a-hole buyer left me a negative for a package that the post office lost, even though the buyer did not purchase insurance or tracking and I STILL gave her a full refund (including her shipping). I disputed the negative, which of course was a waste of time. They always side with the buyer. I mean, what more could I have done? I shipped the package quickly and refunded her money, though it wasn't my fault that the package got lost.
I felt better after at least getting to tell the rep that the people who run ebay are idiots.
