You cannot call them, there's no phone number for eBay, it's a Call Back option, I will provide details for this below, as it seems access to your account is needed.
Just one more check to make and use a laptop / PC for this, check all 5 addresses are correct here in link below, I know you have checked, but do one last check before having to wait for CS to answer.

Then, if you need to, 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.
I recommend contacting CS first thing in the morning as there's more chance of Dublin answering.
