Unauthorized charges for Dri Avg Technol

I was charged today for 1. Dri Avg Technol $32.79 and also 2. Dri Avg Technol $21.94
I did  not authorize these charges.  I have  not subscribed to any Avg services.  I had 2 subscriptions but I cancelled them and received emails stating confirmations to the cancellations.  Why am I being charged and how do I get a refund?
