AVG Subscription

Hello Alfred,

We acknowledge your refund request.
There is no subscription or recent charge found under your *****@yahoo.com account.
The recent charge might have happened due to auto renewal for AVG products registered on a different account of yours.
To locate that account, we have sent an email for you to provide the possible email address that you would have used.
If the email is not found in inbox do check in spam and junk folders.
Thanks.

I was informed on September 12 that my credit card was charged $5.29  for a subcripition I don't have.  How do I get a refund and cancel the account with AVG?
