We are members like yourself with no access to your account, so you will need to contact eBay Customer Services again, but I recommend to do so only very first thing in the morning when the lines first open at 8 a.m. on weekdays, and at 9 a.m. on weekends, as there's more chance of Dublin answering.
With full access to your account, they should be able to explain this payment.
This is the easiest and quicket 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.
As said I do recommend contacting CS very first thing in the morning, when the lines first open, as there's more chance of Dublin answering.
