eBay Customer Services do not have an email address.
I believe Live Chat and Call Back are both still available through the Help and Contact link at the top of the page.
Do you really need to contact eBay?
Most questions can be answered on the Help pages, or better still, providing your issue is not to do with your account or is personal, if you put your problem here someone will probably give you a better answer sooner than eBay CS.
