First check in your eBay profile, link below, that your email is correctly registered, maybe it's something simple, like a space or full stop missing / added ?

There is no email for eBay for answering general questions, it's a Call Back option. I also strongly recommend contacting CS as below, first thing in the morning when the lines first open for ' live agents' 8 a.m. on weekdays, and 9 a.m. on weekends, then there's more chance of Dublin answering. You will hear if it's the dulcet tones from the Emerald Isles, only speak to them. Hopefully, they can see where the error lies.
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.
