You may be better off asking your question here to get suggestions from experienced users.
To contact eBay, use the chat assistant to request a chat with an agent or a call back by starting on the Help & Contact page and following the links for your issue.
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.
