This is the easiest and quickest way to contact eBay Customer Services, for a Call Back option.
 
https://www.ebay.co.uk/help/eua?id=5275&mkevt=1&mkpid
 
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,  you could bac here, explain the issue you are having, there are many very experienced members, who'd be happy to help you.
