My Child’s Phone Has Been Charged For The “VPN Lumos – Weekly Premium”

My child’s phone has been charged for the “VPN Lumos – Weekly Premium” subscription through Google Play without my knowledge since September 2025. I only noticed these charges on 29 August 2026, and the total amount paid so far is approximately 36,000 yen. After realizing this, I immediately cancelled the subscription, but I find it unacceptable that such an ongoing paid subscription on a child’s phone could continue for such a long period without clearer notice or protection mechanisms. I request that VPN Lumos review this situation and refund the unjustly charged amount as much as possible, and also take steps so that similar issues do not occur easily on children’s devices in the future.
