Contact eBay Customer Services, they have full access to your account, and can advise you what is there left to be paid that is stopping you from closing your account. It could be a Fee Credit? That, they owe you money! That would also stop a closure too.
Contact them this way.
Scroll to the very bottom of the page on the link below you will be able to access eBay Customer Services via a Live Chat and sometimes there is a Call Back available. Both options will give you an approximate waiting time, it is usually only a few minutes.
