Sorry, no one here can phone you.
If you wish to contact eBay Customer Service it's a Call Back option.
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 do recommend contacting CS very first thing in the morning, when the lines first open, as there's more chance of Dublin answering.
However, come back here, explain what you are trying to ask the buyer, what is the issue, someone here may be able to help you.
