You may be better off asking your question here or on the Irish community site to get suggestions from experienced users.
To contact eBay, use the chat assistant that you reach from the Help & Contact page to request a call back.
What options you see may depend on your particular issue and how busy that department is at the moment.
Try entering "agent" into the chat window. You may have to provide some context to reach the correct department. If you see a "Still need help?" or "More options" choice, either of those should lead to a call back option.
