More important than an email, is the item in your purchases?
If it isn't in your purchases then you did not buy it, so you can't pay even if you wanted to.
Did you receive an advice in Ebay messages, and how was the emsil addresses,
was it addresses to you by name, or just something like Dear Customer as all messages from ebay address you by name.
If not addressed by name and not in your purchases, then forward email to spoof@ebay.com
If you still need to speak to ebay, go to top of page, then scroll down for contact options.
