I need to change the billing info on a Yahoo! Directory listing ... and went to this Help page (http://help.yahoo.com/help/us/sponsor/sponsor-18.html) and found this email address: email@example.com
The message I sent to that email bounced back as undeliverable. I don't know how to contact Yahoo! about this. I do not have the original info from when the listing was purchased, so none of the automated forms work for me.
