Sorry, there is no phone number for eBay, the main line of communication is with eBay's main Customer Service based mainly in the Philippines via a Live Chat, or sometimes there's a Call Back to select.
You could just come back here, explain the issue you have, there are many very experienced members here happy to help.
Otherwise, to Contact Customer Services, I find the quickest way to contact them, either for a Live Chat, or you can select to speak and request a Call Back, to click on this link:
