Accidentally bought something from the app?

I just accidentally bought a subscription token from twitch in the mobile app (iOS). I just didn't have any credit at all. I got the token anyway. Am I in the minus now?

It is either billed to your mobile phone bill or via a koto / credit card that you have deposited at some point

I actually thought that I was forwarded to Sofortüberweisung or something, but was just not so xD

and other means of payment I have never deposited, only the remaining 19ct from AppStore were deducted from me

am I then in the minus?

I guess you will get a bill, or that Twitch will contact you in some other way.
