There is no email for eBay it's a Call Back option. If you were trying to contact Customer Services before 8 a.m. the lines are open, but it's an automated response.
Contact them now, lines opened at 8 a.m. for actual agents to respond , and there's more chance of Dublin answering now.
This is the easiest and quickest way to contact eBay Customer Services, for a Call Back option.

Lines open 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.
I recommend contacting CS first thing in the morning as there's more chance of Dublin answering.
Or, come back to us here , explain the issue you are having, there are many very experienced people here happy to help you.
