It should take less than a minute. I thought I'd been shafted by the site, but eventually discovered that verizon.net now has a spam filter (courtesy of the AOL email they put in place when they sold the FIOS customers in Texas and Florida to Frontier).
If you have an alternative email (work, etc.) at a different domain, you could re-register under a different name and email address. I did this prior to finding out there was a SPAM filter I was never informed about.
I think VW also modified the site to resend the email if you have not completed registration and you try to log in. It won't get you logged in, but it will get the email sent another time.
