There is no phone number for eBay it's a Call Back option .
You could come back here and explain the issue you're having it could be quicker and more accurate, there are many experienced members here happy to help you.
To Contact Customer Services I recommend using the link below for a Call Back option, and call as close to 8 a.m. on weekdays as possible, as there's more chance then, of Dublin answering.
