My credit card got charged today for buying Coins... I haven’t played since Sept. 28th

So this isn’t a big complain, it was for 100 coins. But today while checking my bank account, I got a charge a few hours ago of $1+ on iTunes for buying 100 coins. Thing is, I haven’t played PoGo since last week. I had to check my journal to check when was the last time I had spun a ‘Stop or caught a ‘Mon.

I’m not gonna fight Niantic about it, of course, since it’s just a measly 99 cents plus tax.

But has this happened to anyone else? It’s less of an annoyance and more of a concern that the app will charge you for things you haven’t done so I’m cautiously uninstalling for now until I come back to play it again.
