Scam

I just got connected to so called Norton Security Tech support.  They used Teamviewer software to get into my computer and told me that I need to pay $299.00 for them to fix the program I had and to give me two year support service.  Is it regitimate?  They already got into my computer but I refused to accept their push in the end.  Is my computer still safe, or did they get my data and information?
