Hello Jean.
We acknowledge your refund request. You've been charged EUR 49.99 on 9th March 2019 for AVG TuneUp - Unlimited (2 years subscription). This is not a renewal order which means you or a family member who have access to your card ending with 3991 has placed this order willingly. I've sent an email concerning your refund request to your registered email address, please check your inbox and spam box as well.
