I've just checked Chat and there's a 2 minute wait, perhaps you were trying to contact eBay Customer Services when lines were not opened they open at 8 a.m. on weekdays.
Try now and there's a good chance Dublin will answer. They are the ones with access to your account which is needed here.
To Contact Customer Services it's a Live Chat, or you can select to speak and request a Call Back. Click on this link:
