Up pops the usual ebay page signed in which I completed with my password.

NEVER respond to anything in your e-mail inbox from "eBay" unless it is in your eBay Messages inbox. Delete everything in your e-mail from eBay that requires you to respond, especially with login information. ONLY respond through eBay's Message system. If it ain't in your eBay Messages then it's a phishing expedition by a scammer.
If you're still in doubt, forward it to eBay and await a reply:
