No one else is reporting this, but do try CS again and only very first thing like now if you can, when the lines first open as there's more chance of Dublin answering. If it's a specific issue with your account they can pass it onto to the relevant tech team to view.
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.
As said , I recommend contacting CS very first thing in the morning, when the lines first open, as there's more chance of Dublin answering.
