Easy money theft

I downloaded the app and about a week later, got a pop up on my phone confirming that I have subscribed to the battle plus game, and that R7 per day will be added to my account. There was no way that I could cancel this, no cancel option anywhere. This is theft. It was pushed down my throat, i have never played a game on my phone, and never wanted to play a game on my phone before. My only option was to phone them on Monday morning to cancel from their side. The lady I spoke to told me that I can phone *155# to cancel such a service in future. This is very bad, taking advantage of people's ignorance, and I'm just wondering how many people have been caught and ****** from. I am disgusted. I have removed their app.
