AUTOMATIC RENEWAL

I had a problem with not being able to access the internet. Microsoft had to remove the automatic renewal of my antivirus subscription because of compatability issues with the symantec version. How do I get my antivirus reinstalled on my computer without being charged again on my credit card? Why can't a person call to ask a simple question. I have been trying to make contact with a warm body to talk to while my computer is without security measures! Help!
