Problem with my subscription

Please help

 

Norton Internet Security stopped working after Windows 7 went south & I had to restore it.  Norton then locked up with an "unspecified error", and said I must remove it and try a reinstall.  Well I did that, and now when I try to bring it up, it says I must buy more time.  Well yesterday, it showed I had a year left. 

 

Who do I talk to to get this straightened out?

 

Please provide phone number, email address or similar so I can get this resolved quickly.
