I got billed again

Hi Johnny.
We can assure you that we have not processed any unauthorized payments from your card or account.
Unfortunately, I could not find any records of this charge under the email address that you used to contact us here.
I have sent an email requesting more details, please revert it containing this details to assist you further.

To whom it may concern,
 

I got a credit card statement saying I paid for DRI*AVG TECHNOLOGIES  $21.99 USD about  2,460 yen. I didn’t order anything and I remembered canceling this order last year and got my money back. I’m not using your product anymore and why are you still charging me.
