OK, not sure what's causing your difficulties.
You could try contacting the Siteadvisor team directly. There's a form linked in the sticky at the top of this forum: http://community.mcafee.com/showthread.php?t=217274
Or, you could call Customer Service directly (toll-free) and tell them the difficulties you are having getting connected to Technical Support. They may be able to patch you through.
1-866-897-9325 press 4 then 0 between 8am & 8pm Central Time.
Meanwhile hopefully someone form the team will look in here anyway.
