Recurring charge

I was charged $74.89 as a recurring charge to my credit card under Dri*Avg Technologies on 9-5-19 but my AVG anti virus says I am using the Free version.  When I log into my account it says to add activation code - but I do not have one.  I would prefer to have the monies refunded and continue to use the free version.  How can I get help with this?
