can't log onto Account.Norton.com

I'm trying to change my credit card information for automatic billing for Norton Internet Security for the upcoming year, so I provide my email address and my password and the Account.Norton.com website says my password is invalid.  I then provide my email address password as requested by the website and click on the 'forgot password link and get a message stating that a message has been sent to my email to facilitate the 'changing' of my password.  When I look to my email account, there isn't any link from Norton to do so.  I then try to create a new Norton account and Norton says an account with that email address already exists.  I'm quite frustrated.  And I'm real tired of constantly having to prove to Norton that I'm not a computer.

 

Help!
