eBay need to send you 2 micro deposits for you to receive, and confirm back, this is the usual method.
Contact eBay Customer Services if these have not been sent, or if they need any other form of ID to be presented.
Contact them now, and 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 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.
