Contact with eBay Customer Services is either through a Live Chat, or sometimes, there's a Call Back system to select, when the lines are not busy.
To Contact Customer Services, I find the quickest way to contact them, either for a Live Chat, or you can select to speak and request a Call Back, to click on this link:
