You do need to contact eBay Customer Services and to speak as you say to a ' human'.
All I can suggest is to contact them very first thing in the morning when the lines first open at 8 a.m. on weekdays, and 9 a.m. on weekeneds, there's more chance of Dublin answering, and more chance of the Call Back option being available, and there's usually then only a few minutess wait, to connect with an agent.
To Contact Customer Services it's a Live Chat, or you can select to speak and request a Call Back. Click on this link:

On the left sidebar you can see Have us Call you or Chat with Our Automated Assistant.
On weekdays lines open between 8 a.m. and 10 .m.
On weekends they open between 9 a.m. and 6 p.m.
