Have you signed up for eBay's Managed Payments? These few pence may be micro deposits ?
If you still need an answer and as access to your account is needed , you'll need to contact eBay Customer Services. Lines are opened now but it's an automated assistant, advisable to wait for agents when lines open at 9 a.m. today contact then, as there's more chance of Dublin answering at that time.
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 do recommend contacting CS very first thing in the morning, when the lines first open, as there's more chance of Dublin answering.
