If you are sure no one in your household has access to your account or made a Guest Purchase, these will not show in your eBay account, then contact eBay Customer Services who have full access and can explain this payment.
This is the easiest and quickest way to contact eBay Customer Services, for a Call Back option.

Lines open for ' live agents' 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.
