Sorry we have no access to your eBay or bank accounts, we are members like yourself.
Check your Purchase History page? Any purchases there?
If not, or there are , and you don't recognise them, and no one in your household has access to your account to buy from eBay, then contact eBay Customer Services, they do have that access to your account, and can explain any payment made, for you.
This is the easiest and quickest way to contact eBay Customer Services, for a Call Back option.

Lines open between 8 a.m. to 10 p.m. on weekdays.
9 a.m. to 6 p.m. on weekends.
I recommend contacting CS very first thing in the morning, when the lines first open, as there's more chance of Dublin answering.
