There is no email eBay readily answer to, it's a Call Back system, and out of hours its an automated chat.
I recommend contacting CS very first thing in the morning when the lines first open for ' live agents' at 8 a.m. on weekdays, and 9 a.m. on weekends, as there's more chance of Dublin answering.
This is the easiest and quickest way to contact eBay Customer Services, for a Call Back option.

Lines open for ' live agents' 8 a.m. - 10 p.m. on weekdays
9 a.m. - 6 p.m. on weekends.
Automated agents will be available on chat outside of the above hours.
