Don't think it's a glitch but perhaps something missing from your selling account set up.  You do need CS to investigate this for you.

I know you've spoken to several CS agents,  but the sad truth is,  you do have to get a ' good un'  to answer some questions!

I strongly recommend contacting CS 8 a.m. on a weekday when the lines open for ' live agents' as then, there's more chance of Dublin answering.

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.
