How were you able to appeal this? I've been searching for a way to
appeal a payment dispute but the only thing I can find is appealing
cases within ebay...nothing for payment disputes which involve financial
institutions outside of ebay.
I hope you had better luck than me! I had an almost identical situation
happen to me (luckily not nearly as much money as you). I have been
selling for a long time and have excellent feedback. Buyer wanted to
return simply because they didn't like it...
