As well as trying the phone number that twyn's  posted, you could also try sending a private message to eBay through one of the following sites.

These are always recommended on the US forums as apparently they're answered by experienced eBay staff, completely   different  to those you've been dealing with.

"My outrageous fees clearly aren't going to seller protection, there isn't any!"

There's plenty of seller protection for FAKE TRACKING SCAMMERS.

Just ask any  victim on any eBay  site who's asked for help.

It's extremely hard,  often impossible,  for them to receive a refund, with eBay taking the scammers' side.

Good , honest buyers and good , honest sellers are leaving  eBay regularly  as they've had enough of eBay doing absolutely nothing (except supporting them)  about all  the scams and scammers
