Auto Renewal renewed for 1 licensed installation, But I want to put on 2 computers

Norton just auto renewed today for 1 licensed installation, but I now have a 2nd computer that needs anti virus....How can I install on both computers and will I be charged again.  I would prefer to have a phone # to customer support, because I am having trouble with my keyboard on this computer!!  Please just give me a phone # to a LIVE person!  Thanks!
