Can't get refund because eBay won't let me close a case

Seller dragged request for a refund out for a month, so I opened a case.


Seller then tried to refund and it failed because case was open (why on Earth would eBay prevent seller from solving the problem when a case is open?!)


Tried to close case, but eBay won't let me.  I select why I want to close the case, fill in the comment, and then hit "Close case".  Takes me to a "Page not responding" page.  It did this several times yesterday, and again several times today.


It suggests accessing the page via the home page directly, which I did.


It says to wait 15 mintues, which I have.


I also tried deleting all cookies and it still didn't work.


It says to check their announcement board to see if the feature is currently unavailable.  This link goes to a page that doesn't exist with a 404 error!


Get your act together eBay, this is a total mess.  You are actively preventing me from resolving a case!


A quick search shows many others have had exactly the same problem.  I'm yet to find any posted solutions though.
