This is a scam. Was downloading a telco app and Activate VPN suddenly appeared. Thinking it was part of the telco app, I downloaded and was charged US$1.25 without being told there was any charge to begin with. The payment was charged via BRWCSPAY.COM and I checked that it was an adult entertainment site. When I was on chat with them to cancel, I realised I had subscribed unwittingly to their monthly subscription of US19.99. They kept pushing for subscription at 50% off and when I rejected they gave a further discount. Finally got them to cancel but unsure of how my card was compromised in any way.
