You are not speaking to eBay here, but to other members like yourself.
If the fee ( Classified listing for a car perhaps?) is not being taken from your registered back up source, usually your bank account, first check those details are correctly added here:

If all seems in order, and there is still demand to pay, contact eBay Customer Services, who do have access to your account and can help settle this fee payment for you.
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.
