Unauthorized charge to my acount

Hello Oscar,
We are here to help you. We have already initiated a refund for AVG Ultimate renewal. The refund USD 106.24 will get credited to your account in 7 business days.
This order was placed because you agreed to automatic extensions of your Subscription Period when you originally purchased your AVG Ultimate on 2017-12-23. We can assure you that we have not processed any unauthorized payments from your card or account.
We sent an email notification 30 days prior to the order being placed to let you know in advance that this payment was due. This also contained information on how to cancel your Subscription.

I have been charged $106.24 to my account for something I did not authorize; however, I would like to know how, when and where did you get my account number as you have posted the charge to a brand new credit card number. 

Please issue me a refund of the whole amount charged as soon as possible.

Thank you

Oscar Ramirez
